Page "5 / 16 ". | Version of – October 15, 2025 – YRI_SD_RUNTIME_VERIF : C ++ Functional Library for specifying " SDMM " YERITH r&d 1 Motivation for SDMM’s Runtime Monitoring Verification Library ” YRI_SD_RUNTIME_VERIF ” 1.1 A Sample Use–Case Scenario of ” SDMM ” 1.2 WHY DO I NEED FORMAL METHODS I HAVE interest in developing mathematical definitions and demonstrations for formal methods for following reasons : 1. any developer and / or BSC student can write code that compiles, run, and has JUnit classes testing code that passes. In effect, JUnit tests only stipulates that a running program does what a programmer had in intent; BUT not by any means exactly what a stakeholder needed. 2. BUT what demonstrates that the written and running program does what the primordial first intent of the developer and of his stakeholders was !? 3. THIS is exactly what formal methods (mathematics for computer science oriented towards testing and verifying; making sure, that a software program does what its intent is) does. 1.2.1 ” C ++ library YRI_SD_RUNTIME_VERIF ” : Expressing of sequencing of actions in time (temporal usage rules for system safety) Specifying temporal usage rules for system safety is primordial for ensuring a proper quality assurance of a system that is aimed to be more productive and safer in its usage by users, and / or maintainers. THIS is why we created the C ++ library YRI_SD_RUNTIME_VERIF . " YRI_SD_RUNTIME_VERIF " is an acronym for YERITH_State_Diagram_Runtime_Verification . 1.3 Comparison with Unit Testing 1.3.1 Unit Testing UNIT TESTING [ Zel20 ]; [ Nou09 ] ( https://www.zenodo. org/record/8052444 ) consists in creating System Under Test program execution sequences with certain data & certain test criteria so to assert following statements over a program under test : 1. a specific input data in a unit test module method generates a pre-defined certain output data; Thus developers must provide test input data for each test case runtime execution. UNIT TESTING is a kind of what is called : ◦ White-box testing [ Zel20 , MYE20 ] ; meaning a developer knows intrinsics (inside details) of the system-software under test; ⇒ Another kind of testing is called BLACK-box testing [ Zel20 , MYE20 ] ; meaning a developer doesn’t need any inside source code details knowledge of the system-software under test. Sample unit testing frameworks are for instance : a ) JUnit testing framework ( https://www.junit.org ) for JAVA programs; b ) Qt Test testing framework ( https://doc.qt.io/ qt- 5 ) for Qt Graphical User Interface programs; YRI-DB-RUNTIME-VERIF [ NN25 ] ( https://github. com/yerithrd/yri- db- runtime- verif ) is a simpler and more offering alternative; especially for software integrating testing (See Subsubsection 1.3.3 ) ! However, it is more appropriate for people with a strong mathematical background (set algebra & formal methods); c ) CppUnit testing framework ( https://freedesktop. org/wiki/Software/cppuni ) for C ++ software. 1.3.2 Automated Unit Testing Automated Unit Testing consists in automatically generating a System Under Test program execution sequences with certain data & certain test criteria so to assert following statements over a program under test : 1. a specific input data in a unit test module method generates a pre-defined certain output data; Thus developers receive automatically test data & test cases for each test case runtime execution. Such generator systems like for example RT-Tester MBT ( https://www.verified.de/products/ model- based- testing ) from ”Verified System International GmbH” ( https://www.verified.de ), generally require a specification of the software and / or program under test; So to be able to perform the automatic code source generation for the Embedded Unit Tester " RT-Tester MBT (Model Based Testing) ". RT-Tester MBT , for example, inputs a ”David Harel Statechart ” (See Subsubsection 1.6.1 ) specification as for instance generated by a plug–in for ”Borland Together 6 ” , delivered as a by–product by ”Verified System International GmbH”. A detailed algorithm and function description of RT-Tester MBT could be found in Subsection 1.6 ! 1.3.3 Runtime Monitoring Verification RUNTIME MONITORING Verification with state diagram mealy machine on the other side consists in : 1. specifying a wrong system under test program logical sequence using a mealy automaton as defined for instance in Subsection 1.5 ; 2. it is possible to specify conditions that trigger event between SDMM states : guarded condition ; A guarded condition is placed between squared brackets (’[’guarded_condition’]’) . Example : ->[in_sql_event_log(’guardedevent’,STATE(d))]/’event1’-> The previous example guarded condition ( in_sql_event_log(’guardedevent’,STATE(d)) ) transition means that : ’event1’ occurs only if event ’guardedevent’ has previously occurred and is an element all events that lead to mealy machine state STATE(d) . The arrows signs (’->’) around depicts this is a transition. 3. YRI-DB-RUNTIME-VERIF observes monitors the SUT and emits all events as described and specified by developers; Thus developers don’t provide test cases and / or test data ! Developers execute normally the System Under Test, by providing a normal system execution time run. Author: Xavier Noundou [Pr. Prof. Dr.–Ing. ] Holy-Ghost. YERITH– NISSI . (JEOVAH–NISSI IN HEAVEN.)

" SDMM " is a textual (See Figure 4 ) and graphical (See Figure 1 ) representation of software system requirements; HOWEVER, requirements expressed using " SDMM " are fail (forbidden) requirements : I.E., software system execution run that shall never happen ! ◦ During software development, developers need to characterize effects of program statements onto software program behavior. For instance, what causes the deletion of a database table column department value at the level of the software user– scale (Example in Figure 2 ). Figure 2 could also be represented by a state diagram mealy machine as illustrated in Figure 1 . 1.4.2 Advantages ◦ WHITE-box as Well As Black-box testing is possible and / or available at once for any developer in testing; Depending on how YOU specify your runtime monitoring diagram & code (See Section 4.1 ). ◦ Software developers could implement code source checking of LTL–model checking formulas ( https: //www.wikipedia.org/ ) for their fail (forbidden) program requirements; I hope to also have sample LTL–model checking formulas implemented in future releases of YRI-DB-RUNTIME-VERIF , which is a runtime monitoring verification container provided to work with the " YRI_QVGE Design & Verification System" . ◦ Software developers that create & maintain fail (forbidden) program requirements mustn’t have a perfect knowledge of code sources of the System Under Test. 1.4.3 Cases of Practical Usages of ”SDMM” ◦ Automobile industry ”car–automobile–breaking safety & security usage rules” on–the–fly to avoid thousands of car–recall because of a bug (E.g.: Toyota Camry 2009 ( https://https://en.wikipedia.org/wiki/ 2009%E2%80%932011_Toyota_vehicle_recalls )); A car defect could only just be fixed at any Toyota registered auto-car-dealer by inputting a ”SDMM” fix specification into an in–car placed YRI–QVGE–PC–Tablet device; Instead of sending it back to a Toyota car factory ! 1.5 State Diagram Mealy Machine : Brief Summary Explanation " YRI_SD_RUNTIME_VERIF " has following usages and advantages: I . ) Formalism STATE DIAGRAM mealy machine for system specification: Mealy Machines are kind of state machines where output states depend only on input on a source state. STATE DIAGRAM mealy machine as defined by myself is a finite state automaton that only has following characteristics: a.) Each automaton / machine only has 1 start state S 0 , and 1 final state S f that is an accepting / error state. A final, accepting, or error state is a state that shows a defect status of the system under analysis (SUA / PUA / SUT). b.) Each state S i only has 1 outgoing state transition to an output state S 0 . c.) Each transition T , except a start transition ” start ”, could have a pre-condition, and post-condition ; That both are called or named state-edge-condition ( pre-condition on T 1 : ” T 1 ”; post-condition on T 1 : ” T 1 ”). A state S i has a state–condition either as pre- condition ” T 1 ” on a state transition Or as a post– condition ” T 1 ” of a state transition T 1 . In Figure 1 , state–conditions are for instance ” Q 0 ”, and ” Q 1 ”. Each state–condition ” S i ”, and / or pre–condition; And / or post–condition is an algebra set specification that uses set inclusion operations : ∈ , / ∈ . d.) A set inclusion operation as state–condition for a state S i could for instance be : 1. ) Q0 : = IN_BEFORE(y, D) is to read “BEFORE next event, variable y is IN set D ( y ∈ D )“ . THIS boolean first–order preposition is assigned into variable Q0 ; the ”underlining” illustrates that this is a pre–condition : ” meaning a condition That shall hold before (PRE) next event to occur in software system. ” 2. ) Q0 : = IN_AFTER(y, D) is to read “AFTER next event, variable y is IN set D ( y ∈ D )“ . THIS boolean first–order preposition is assigned into variable Q0 ; the ”over-lining” illustrates that this is a post–condition : ” meaning a condition That shall hold after (POST) next event to occur in software system. ” 3. ) IN_BEFORE_NOP() : THIS boolean first–order preposition means that this pre–condition ( ’True’ ) holds before (BEFORE) next event to occur in software system.” 4. ) IN_AFTER_NOP() : THIS boolean first–order preposition means that this post–condition ( ’True’ ) holds before next event to occur in software system, after (POST) previously occurred event.” 5. ) NOT_IN_BEFORE(y, D) 6. ) NOT_IN_BEFORE_NOP() 7. ) NOT_IN_AFTER(y, D) 8. ) NOT_IN_AFTER_NOP() I I . ) A C ++ library that implements runtime monitoring and fail–state recovery as a static library : ( https: //www.github.com/yerithrd/yri_sd_ runtime_verif ).

In comparison to statechart [ HarXX ], which is a visual formalism for states diagrams, YRI_SD_RUNTIME_VERIF doesn’t support at time for instance the following features: hierarchical states (composite state, submachine state), timing conditions . A sample state diagram mealy machine is pictured in Figure 1 .

Sample model checkers are NuSMV ( https: //nusmv.fbk.eu/downloads.html ); SMV ( https: //mcmil.net/smv.html ); Spin-model checker ( https://spinroot.com/spin/whatispin.html ). 1.6.1 David Harel Statechart : A Visual Formalism for State Diagram Figure 9: A Sample David HAREL–Statechart model of the temporal property expressed in fig. 4 : — ” Whenever department YRI_ASSET was deleted (event ’DELETE.department.YRI_ASSET’); querying stock table shall not find again an inventory stock in any department named YRI_ASSET” —. entry / PostEvent(’DELETE.dept.YRI_ASSET’) dept_exits dept_exists’ entry / PostEvent(’SELECT.stocks’) ’SELECT.dept’ ’SELECT.stock’ Statechart [ HarXX ], as defined and proposed by David HAREL; Represent diagrams, sometimes composite with internal states that are used to describe reactive systems, meaning systems that react and act based on environmental input and interaction.

( https://www... ) Timed Discrete Input / Output Hybrid System (TDIOHS) as defined by Peleska et al. [ BFPT06 ] implements David-HAREL statechart full compatibility incorporating the following elements for software system specification & elicitation : 1. ) A software system behavior and actions can be represented as finite set of configurations; A configuration is an assignment of variables to values that situates a software system evolution over time; 2. ) A set of configurations of a software system as a finite states graph representation where nodes represent software system states, And edges represent transition between software system states; 3. ) Start– & End– (Final–, Accepting–, Erroneous–) state to represent INITIAL & FINAL software system state. A reactive system has a particularity that it doesn’t define a final-accepting state as it continuously reacts with its environment : it loops around its start state; 4. ) Software system states transition defined as graph–edge between software system configuration–states; 5. ) Software system state transition ”Event” as label between graph–nodes; 6. ) Guarded condition as behavioral condition that must hold in order for a state transition event to trigger & thus send the software system into a new configuration; 7. ) Timing condition 8. ) hierarchical states (composite states, submachine state) 1.6.2 Timed Discrete Input / Output Hybrid System (TDIOHS) Figure 10: A STCT–symbolic test case tree randomly generated by manual drawing for explanation purposes. 0 N TDIOHS–Timed-Discrete-Input-Output-Hybrid- System [ BFPT06 ] is a statechart compatible state diagram formalism defined by "Peleska et al." at the University of Bremen in Germany. "Peleska et al." define a test mechanism to generate test cases from TDIOHS statechart visual description; The generated test cases abide to "Marie–Claude Gaudelle" algorithm defined in [ Gau06 ] to statistically and uniformly-distribute test cases around a tree that describe all potential program code execution paths : STCT (Symbolic Test Case Tree). A System Under Test (SUT) tree execution paths could then be traversed based on the real test data generated by a symbolic test data generator component as illustrated for instance in [ nf10 ]. A sample STCT is illustrated in Figure 10 ; ” N 0 ” is a start node of the program tree. 1.6.3 TDIOHS in Action within ”Borland Together 6 ” with RT– Tester of ’ verified.de ’ Xavier NOUNDOU, myself, wrote together with Verified Systems International GmbH a plugin that enables developers to automatically create C ++ testing code for design drawings created in the CASE-Computer Aided Software Engineering Design tool Author: Xavier Noundou [Pr.

I performed this task under supervision and advising of ”Jan Peleska”, as a student in Computer Science at the University of Bremen in Bremen–Germany in years ” 2004 / 2005 ”. Based on the automatically generated C ++ module code, a developer could then use the UNIT Testing Framework for embedded systems RT-Tester of Verified.de ( https://www.verified.de/products/ model- based- testing ) to create software module unit testing code with following criteria : 1. ) MCDC (Modified Condition Decision Coverage) : test cases & data for checking any outcome of any boolean assignment of variables involved & used in a conditional IF-Then-Else branching statement; 2. ) Uniformly statistically distributed test cases [ NN07 ] & test data [ nf10 ] from all possible test runtime execution of the Program Under Analysis (PUA) [ NN07 , BFPT06 ] ; 3. ) Myself I only received " 2, 000 Euros" as fund collected as money–rewards–intellectual property out of this work since ”May 2007 ” when I delivered program code software as part–deliverable to acquire my ”Diplom–INFORMATIKER” qualification from the department of Mathematics & Computer Science (”Fachbereich 3 ”) of the ”UNIversity– racist of Bremen–Germany”. 1.6.4 TDIOHS in Action by ”Automatic Test Cases / Data Generation” Master Thesis [ NN07 ] in Computer Science of ”Xavier N. NOUNDOU”, at the University of Bremen in Bremen–Germany; demonstrates an implementation of uniform distributed statistically algorithm for selecting paths for creating test cases from a Statechart designed in ” Borland-Together 6 ”. The statechart is first of all transformed into a Symbolic Test Case Tree ( STCT ) before ”MARIE-Claude Gaudelle” [ Gau06 ] modified algorithm by [ NN07 ] is applied. In [ CHKS12 ], Tatiana Mangels & Jan Peleska present "CTGEN" , a Unit Under Test (UUT) test cases and test data generator for embedded system writen in the C programming language. More information and contacts for buying and / or trying this software product can be found at following URL : https://www.verified.de/products/model-based-testing , from the German society ”Verified Systems International GmbH” . 2 Mathematical Formal Definition of SDMM THIS section gives a mathematical theoretical definition of state diagram mealy machine (abbreviated ” SDMM ”), as conceived originally by us for our project YERITH–ERP– 9.0 [ Nou22 ] runtime monitoring verification started in year 2015 in Yaounde Cameroon. YRI_SD_RUNTIME_VERIF ’s formal description of the state diagram formalism follows Mealy machine [ Wik22 ] added with accepting states (final or erroneous states), and state diagram transition pre- and post-conditions : ” state diagram mealy machine ”. Another excellent, detailed with proofs and theory presentation of mealy automata [ PlH21 ] is available. In comparison to statechart [ HarXX ], which is a visual formalism for states diagrams, YRI_SD_RUNTIME_VERIF doesn’t support at time for instance the following features: hierarchical states (composite state, submachine state), timing conditions . 2.1 Definition 1 : A state diagram (for mealy machine). A state diagram is an 8 –tuple ( S , S 0 , C , Σ , Λ , δ , T , Γ ) where: • S : a finite set of states • S 0 ∈ S : a start state (or initial state) • C : a set of predicate conditions; pre-conditions are underlined (e.g.: Q 0 ), and post-conditions are overlined (e.g.: Q 1 ). A pre-condition is comparable to a Harel- statechart guarded condition . • Σ : an input alphabet, Σ := { F a l s e , T r u e } . ′ F a l s e ′ means no input from SUT into YRI-DB-RUNTIME-VERIF . ′ T r u e ′ means any input could come from SUT. • Λ : an output alphabet (of program events e n ( n ∈ N ) ), φ the no program event. A program event generally corresponds to a function or method call at a SUT source code statement (or program point). • δ : S × C : a 2 -ary relation that maps a state s to a state-condition c as either a state diagram transition pre- condition ( c ), or as a state diagram transition post-condition ( c ). • T : S × Σ → S × Λ : a transition function that maps an input symbol to an output symbol and the next state. • : a 2 − a r y relation that maps a state diagram transition to a guarded condition expression. • Γ : a set of accepting states; Γ ∈ S . For instance, for the motivating example described in Figure 1 we have: • S = { D , E } ; • S 0 = D; • C = { Q 0 , Q 1 } ; • Σ = { F a l s e , T r u e } ; • Λ = { φ , ’ SELECT.department ’ } ; • δ = { ( D , Q 0 ) , ( E , Q 1 ) } ; • T = { (( D , F a l s e ) , ( D , φ )) , (( D , T r u e ) , ( E , ’ SELECT.department ’ )) } ; • Γ = { E } 2.2 Definition 2 : A pre-condition. A pre-condition of a state diagram transition is a predicate hat must be true before the transition can be triggered. A pre- condition Q 0 could have 2 forms: • Q 0 : = IN_PRE(X, Y) that means value " X " is in ( ∈ ) database column value set " Y ". • Q 0 : = NOT_IN_PRE(X, Y) that means value " X " is not in ( / ∈ ) database column value set " Y ". 2.3 Definition 3 : A post-condition. A post-condition of a state diagram transition is a predicate that must be true after the transition was triggered. A post-condition Q 1 could have 2 forms: • Q 1 : = IN_POST(A, B) that means value " A " is in ( ∈ ) database column value set " B ". • Q 1 : = NOT_IN_POST(A, B) that means value " A " is not in ( / ∈ ) database column value set " B ". For state diagram mealy machines with more than 2 states , only the first transition has a pre-condition specification ( IN_PRE , or NOT_IN_PRE ). Each other transition only has a post-condition specification ( IN_POST , or NOT_IN_POST ). Since each state only has 1 outgoing (edge) state transition, the post-condition of the Author: Xavier Noundou [Pr. Prof. Dr.–Ing. ] Holy-Ghost. YERITH– NISSI . (JEOVAH–NISSI IN HEAVEN.)

Since all or part of your business data critical are only located on a hard–drive outside of your local area network (LAN), There might be issues with following legal & documentary aspects : 1. Disruption of WAN (Wide Area Network) and / or Internet might prevent you indefinitely to access your business data. 2. LAWS of the country–place where you locate your data might endanger your business; Partly because it is different from your local laws where you officially have registered your business venture ! ON the other hand side of it; Remote location of your business data in a better country–place might favor your business compared to where it is locally registered ! It might be allowed in that remote country–place to perform certain digital ideas and things that are forbidden where your original business is located : for instance PORNOGRAPHY, etc. ! You may expose yourself to legal prosecutions in the latter case; Either in the remote country– place of your remote digital activities–server, Or locally where this digital activity is Prohibited– by–laws !!!

Thick client software system architectures is simpler because it requires less layers in its logical (or physical) software system architecture, and is easier to develop and maintain as a software system application. Table 2.1 illustrates a thick client software system is SUPERIOR IN TERMS OF TOOLS FOR MAINTENANCE AND DEVELOPMENT than a webbrowser based software system ! A webbrowser based software system architecture has more drawbacks as follows: 1. ) it requires at least 2 other software systems, apart from the ones normally required by developed software system itself, for instance libraries (e.g.: Log 4 j ), to fully operate (e.g.: web server, application server, etc.). Table 6.1 depicts this situation in the light of the open source ERP software system Odoo . Accordingly, a thick client software system doesn’t require any running and managing infrastructure such as for example an application server ! 2. ) A webbrowser based software system requires at least 4 layers in its logical system architecture (e.g.: client, presentation, logic, and data layers). Accordingly, a thick client software system only requires at least 2 layers ! 3. ) A webbrowser based software system potentially entails more software security vulnerabilities because its implementation requires the use of at least 2 different programming languages, and frameworks in combination. Accordingly, a thick client software system needs only the use of 1 homogeneous software programming language ! Esprit–Saint. YERITH– NISSI .

Users of YEROTH–ERP– 3.0 could have the following roles: 1 Version of – January 12, 2023 – Esprit–Saint. YERITH– NISSI .

YEROTH–ERP– 3.0 allows for business management tasks (listed in Table 1 ), depending on user role, as follows: 1. create a department (e.g.: finance, asset, stock, etc.) 2. manage clients, and human resources, and suppliers 3. manage enterprise asset (e.g.: cars, etc.) 4. manage financial expenses 5. manage inventory stock 6. manage sales 7. view business dashboards (across sites). 3 Potential Usages of YEROTH–ERP– 3.0 YEROTH–ERP– 3.0 potential usages are: 1. STOCK AND TRADE EXCHANGES MARKET PLACE 2. ENTERPRISE RESOURCE AND PLANING SOFTWARE for supermarkets and commercial stores 3. i.e. ANY NON GOVERNMENTAL ORGANIZATION, or GOVERNMENTAL ORGANIZATION. 4 Advantages of YEROTH–ERP– 3.0 1. YEROTH–ERP– 3.0 is 100% stable 2. YEROTH–ERP– 3.0 has an alert system with two types of alerts: alerts based on stock–quantity, and time– period alerts 3. users have the choice between small size receipts, and, bigger size receipts (”A4”) 4. YEROTH–ERP– 3.0 runs on the Linux operating sys- tem, because Linux is stable, performant, and less vul- nerable to security breaches in comparison to other op- erating systems (’ Windows 10 ’) 5. YEROTH–ERP– 3.0 has an user interface ”Sales” to view sale information (Figure 2 ), and thus enables users to make managerial decisions 6. YEROTH–ERP– 3.0 has an interface ”Business dash- board” that generates financial accounting reports, from sale and payment information, to help managers to make ”business decisions”. Figure 2: Sale–information window. 5 Alert System Users with roles « Administrator » or « Business manager » are the ones able to create alerts. YEROTH–ERP– 3.0 allows its users to create two types of alerts: 1. alerts over stocks–quantities 2. alerts over time intervals (this helps for perissable arti- cles and for sales discounts over a period of time). 5.1 Alerts over Stock–Quantity An alert aver a stock–quantity is a message that is sent to a pre–determined user whenever ”pre–determined” stock– quantity (X) of a specific article–stock is reached. For instance, Xavier (« Business manager ») could create an alert for stock ”mango” that will be trigerred whenever stock ”mango” quantity reaches 100 ; An alert–message is sent to user John (« Storekeeper »). 5.2 Alerts over Time–Period A time–period is defined by a starting–date and an ending– date (dates are from the ”gregorian” calendar). An alert aver a time–pe riod (T) is a message that is gen- erated, sent to a pre–determined user, and kept within YEROTH–ERP– 3.0 from T’s starting–date up to T’s ending– date. For example, an alert with a message has to be sent to Paul (« Cashier ») when the date of May 05 t h is reached. The alert message specifies that a rebate of 20% has to be applied on every sale of yoghourt ’trèsbon’ during a time interval of 2 weeks. 6 Database Management System YEROTH–ERP– 3.0 uses ’MariaDB’ as the standard DBMS. ’MariaDB’ is very stable, very performant, and free– software.

YRIDBRUNTIMEVERIF and yri_sd_runtime_verif don’t incur a run- time supplemen tal o verhead to the SUT, apart from emitting SQL ev en ts from SUT to YRIDBRUNTIMEVERIF as they o ccur, since no hand–shaking mec hanism is used b et ween YRIDBRUNTIMEVERIF and the SUT. The emission of an SQL ev en t from SUT to YRIDBRUNTIMEVERIF do esn’t cost more than 2 statemen ts execution time (getting a p oin ter to the DBUS serv er, and calling a metho d ’ YR_slot_refresh_SELECT_DB_MYSQL ’ or other similar 3 metho ds (for INSERT , UPDATE , and, DELETE ) on it). 14 7 Related W ork • SUT source co de instrumen tation with run time monitor sp ecification. "Clara" [ 12 ] enables to express soft w are correctness prop erties using AspectJ and dep endency state machines (r elate d to tr ac e- matches [ 21 ]) , b oth as instances of the t yp estate formalism, a formalism that is merely used for c hec king correctness of pro- grams b y a static compilation (analysis) tec hnique called typ estate che cking . The Clara framew ork w eav es (instruments), and annotates a program with run time moni- tors using AspectJ , then tries to optimize the w ea ved program b y static analysis. The ”residual program”, meaning the w ea ved statically optimized program is then exe- cuted and run time monitored b y developers to detect run time errors. Run time monitor- ing to ols [ 13 – 16 ] w ork as similar as the Clara framew ork do es. YRIDBRUNTIMEVERIF do esn’t instru- men t the System Under T est (SUT) with an y sp ecification. It runs the run time mon- itor concurren tly from the analyzed SUT, but not with hand–shaking mec hanism, th us not increasing run time execution of the SUT. YRIDBRUNTIMEVERIF sp ecifies the run time monitor as a state diagr am me aly machine , a subset of t yp estate, sp ecified as a C ++ pro- gram, and extended with accepting states and state transition pre- and p ost-condition. • SUT binary co de instrumen tation with a run time monitor. With tracerory [ 6 , 22 ]", Jon Ey olfson and P atric k Lam use run time program binary co de instru- men tation tec hnique in INTELpin [ 23 ] to instrumen t running programs for purp oses of detecting unread memory . I.e., tracerory do esn’t generate itself a run time monitor, it uses INTELpin [ 23 ] to generate a run- time monitor for its v erification purp oses. " Purify " [ 24 ] do esn’t allo w for SUT user cor- rectness prop ert y sp ecification. It has built-in memory access safet y prop erties to c heck offline on program execution, after instru- men tation of the SUT, its third-part y , and v endor ob ject-co de libraries. In con trast, with YRIDBRUNTIMEVERIF , the user instrumen ts the source co de of the analyzed C ++ program at com- pile time with SQL ev en ts emitting co de. YRIDBRUNTIMEVERIF could also b e used to p erform memory write in tegrit y chec k lik e tracerory . YRIDBRUNTIMEVERIF moni- tors program trace ev en ts at database level (also source co de statemen t lev el b y map- ping to SQL query statemen ts), and not at program coun ter lev el as tracerory do es. YRIDBRUNTIMEVERIF inputs a SUT correct- ness prop ert y sp ecification as a state diagr am me aly machine (as a subset of LTL [ 2 ]); YRIDBRUNTIMEVERIF is a run time monitor con tainer; YRIDBRUNTIMEVERIF also gen- erates itself a run time monitor whereas tracerory do esn’t. • Source co de automated test case gener- ation for C ++ with TDIOHS [ 25 ], or FOSS library libfsmtest [ 7 ]. ”P elesk a et al.” created a F ramew ork for generating Harel– statec harts fully compatible state diagrams as T est programs as C ++ ob ject–oriented pro- gram co de; Based on ”P elesk a et al.” formal- ism of Time Discrete Input/Output Hybrid System ( TDIOHS ). TDIOHS mo dels state sys- tems that handle real and discrete real n um- b er data as input to the system under test; TDIOHS mo dels SUT execution b y a so called SYMBOLIC TEST CASES TREE (STCT) that represen ts all p ossible run time execution paths of the SUT b y means of sym b olic test cases data. Sym b olic test cases data are data that cannot b e used in a run time execution, BUT that are generated outside from STCT tree b y a sym b olic test data generator algo- rithm. The SUT sample tree execution paths are then tra v ersed based on the real test data generated b y a sym b olic test data generator comp onen t [ 26 ]. In con trast, the framew ork YERITH_QVGE run time monitors a program under analy- sis only for sp ecified fail (forbidden) trace b eha viors as giv en by users. • Sp ecification as set in terface op era- tions. "Hob" [ 27 , 28 ] is a program v erifi- cation framew ork that enables to: c harac- terize effects of program statemen t on data 15 structures b y means of all ( ∀ , ∃ , etc.) alge- bra abstract set in terface op erations; and to c hec k that these characteristics hold or not, using static analyses. YRIDBRUNTIMEVERIF is a program v eri- fication framew ork that enables to: c haracter- ize effects of program statemen ts via SQL [ 4 ] (Structure Query Language) on database table columns b y means of set interface oper- ations ( ∈ , / ∈ ); and to c hec k that these charac- teristics hold or not, using dynamic run time analysis. • Concurren t Ev en t Stream Analysis. " DejaVu " [ 29 ] enables to c hec k safety temp oral prop ert y expressed in first-order past linear-time temp oral logic (F O- PL TL) for ev en ts that carry data. DejaVu inputs a trace log ( offline ) and a F O- PL TL form ula, and outputs a b o ole an v alue for eac h p osition in the inputted trace. " LogScope " [ 30 ] c hec ks, offline , soft w are systems correctness prop erties expressed using a rule–based sp ecification language o v er state machines. It is not v ery precise what t yp e of state mac hine is created and pro cessed. " LogScope " translates sp ecifica- tions in to C ++ monitors (that could carry data). " EventRaceCommander " [ 31 ] repairs in w eb applications ( online ), even t race errors, a kind of safet y error. States diagrams sp ecifications are implemen ted as C ++ program monitors using C ++ library yri_sd_runtime_verif . YRIDBRUNTIMEVERIF outputs a dev elop er giv en (b y means of a callback function, as seen in ’line 15 ’ in Listing 2 ) string message 1 in case an accepting state w as en tered, and a trace ev en t of YERITH–ERP–3.0 lead- ing to it.

YRIDBRUNTIMEVERIF ev ents also carry data (database table and column name, records quan tit y mo dified by curren t SUT ev en t).

THIS HAPPENED A T NIGHT AROUND 11:00 PM, with BER TRAND, breaking my gate seals with a weapon of some sort (BER TRAND, was the lead thief of DR. CHRISTIAN EYOUM ). THIS HIJ ACK OR A T T ACK on my person happened just 1 day after I denounced to PRC.CM and SHANDY -SHANDY -CABINET .COM (biological father of my mother’s side cousin ANGELA) a fake "BACC ALA URÉA T"-DEGREE from ’ ANGELA TCHAMOU SHAND A OWONA SPOUSE DR.

I ALSO BECAME AN AGENT OF C AMEROONIAN DEFENSE AND SECURITY FORCES ON FEBRU AR Y 14 , 2021 . DR. CHRISTIAN EYOUM after this kidnapping, held me at LAQUINTINIE HOSPIT AL for poisoning me 2 weeks, AND THEN RELEASED AN OFFICIAL DOCUMENT TO MY RELA TIVE ROSE SANGNOU . ROSE SANGNOU has since been using the fake document to go meet my clients to say that I AM A PSY P A TIENT AND THA T THEY SHALL NOT DEAL ANYTHING WITH MYSELF . ROSE SANGNOU also went to meet all my privately–owned real estate properties’ neighbors TO DO THE SAME. I HA VE COMPLAINT BEFORE DOU ALA–NDOKOTI JURISDICTIONAL TRIBUNAL in front of JUDGE HUGUES ALAIN Y AGER MABOMA SINCE FEB. 2021: • 3 convocations have been sent by now to DR.

AFTER 2 WEEKS OF POISONING AND TR YING TO DESTROY MY BODY WITH DRUGS AND PILLS, a yellow clothed (level of BACHELOR OF SCIENCE) gate guard OF ”HÔPIT AL J AMOT ” that I don’t remember the name, tries to SNEAK INTO my private life by calling me on my private cell phone number [ (+237) 6 52 39 69 50 ] every other day . I SAID TO HIM THA T I DON’T ENTER T AIN RELA TIONSHIPS WITH PEOPLE LIKE HIM. PS: THIS GA TE GU ARD, yellow–clothed with an uniform, is of BETI–TRIBE like DR. LA URE MENGUENE MVINDI ! 3.

ROSE SANGNOU insits that we shall meet because she is my mother . I then accept, but refused to meet up her at my private owned property in Y aoundé- Ahala-Nsimbock. W e then meet up first at DOROTHÉE NDJ A TIÉ SHANDA house, then at supermarket ’supermarché carrefour EKIÉ’ in Y AOUNDÉ-ÉKIÉ. THIS PERIOD IS judicial information investigation time, that is mostly why I accepted to meet up with her . I NOTICE with an impression THA T my mother ROSE SANGNOU COULD HA VE BEEN BRUT ALIZED ON HER LEFT KNEE.

THIS VER Y POOR PERSON, both in spirit and financially; whose wife makes money out of cooking food for street workers, COULD SUCCESSFULL Y intimidate people not to come attend work or anything else into my real estate properties. COLONEL (retired) of Army Gendarmerie KÉMAJOU couldn’t lie and convince people that I DON’T POSSESS A Ph.D in Computer Engineering; since his son "Jonas Kémajou" who he also in gendarmerie told me once: "Myself I also POSSESS A Ph.D QU ALIFICA TION WITH NO DEGREE A T HOME" ! I am wondering in Cameroon why army intermediates in civilian life and affairs; THIS DOESN’T HAPPEN usually in rich and developed countries like Germany . This day of Saturday November 18 , 2023 ; while I was talking to a computer technician neighbor named Gabriel T akoumbe, KÉMAJOU came along walking with an indigo "Garde Présidentielle (special unit of cameroon forces attached only for the President of The R epublic.)" T -shirt. COLONEL kemajou tells me HE W ANTS MY PERSON NOT TO WRITE anymore on his forfeitures against myself; in front of at least 7 young men and women, saying He didn’t call my genitor mother any day before. COLONEL kemajou sect named JÉRUSALEM APOSTOLA T , sacks every public entry road to my real estate 2 –storey building (unfinished yet). Yves Landry Galax ETOGA, chief of secret services of Cameroon seems to like to try harassing competent professors of science and technology like myself .

" 04 " December 2023 : I cannot recognized Cameroon where someone high qualified by myself is permanently harassed physically by illegal neighbors like KEMAJOU gendarmerie colonel Criminal. KEMAJOU gendarmerie colonel tries on the street to talk to myself while I am coming back from a hardware shop. It seems to myself that illegal neighbors religious sect "Jerusalem Apostolat" is trying to make confusion about my humble person wherever I go in my life; K emajou gendarmerie colonel has tried around my neighborhood, with help of SECT ARIAN OF JERUSALEM APOSTOLA T ; to make noise that XA VIER noumbissi noundou IS A PSYCHIA TRIC P A TIENT that doesn’t want to take pills ! 38.38 THREA T ON MY PERSON BY ROSE SANGNOU IN J ANUAR Y 2024 ROSE SANGNOU , despite that JUDGE HUGUES ALAIN Y AGER MAB OMA gave her prohibition to come to my home in Y aounde during year 2023 , came by force with someone that I don’t know whereabouts T o my neighbor ”CARINE LELE njougep tchana” T o incriminate her about chairs she owns by now; I destroyed chairs that were not in good shape last year from my humble home by throwing them away outside. It seems ”C ARINE LELE njougep tchana” put them in her personal home without asking myself since I just threw them away; which is normal since They don’t belonged to me anymore ! " 30 " January 2024 : It seems my genitor mother ROSE SANGNOU went to talk to gendarmerie people so they could harass myself to go for an illegal psychiatric treatment; because while I was talking to Justice ”ME. ANDRÉ Mbet” today , I saw 1 gendarmerie man came into his personal office where he also, with his wife, Owns a financial transaction center . I immediately told Justice ”ME. ANDRE Mbet” about this attitude of gendarmerie people coming inside where I perform businesses to make some kind of visual and gesture signs to owners of businesses, So they wouldn’t deal with myself anymore ! " 24, 25 " April 2024 : 1 man wearing a talkie-walkie came across my personal road in Simbock YDE. I went to talk to him since I was looking for a technician that didn’t finish a work in my humble house. F or 6 days now , this technician wasn’t in my house anymore despite myself telling him to finish his work on my steel door . I suspect again justice (”huissier”) SHANDA-DJ A TIE and her spouse P r . JEAN–CL A UDE shanda-tonme to harass my genitor and mother R ose SANGNOU to try to bring myself by force to a psychiatric destructive mind place. JERUSALEM–APOSTOLA T rosicrucian sect tried to follow myself these last 2 days using the brigand ’Moise BA TOMEN’, and another person male, THA T i don’t know whereabouts but that live behind ”Carine Lele Njougep T chana” house for at least 6 months from now backwards in time ! Just 1 month before, I was stopped from walking by to our main official road by a sectarian female of Jerusalem–APOSTOL A T .

APRIL 30 , 2013 JAVA application server ” Quercus ” — JAVA – PHP –interpreter PROGRAM analysis of web apps SOFTWARE cyber –security ◦ “ [THIS course CS 846 project led by Professor doctor Frank TIP] , was about creating a security taint analysis program code in JAVA for the ” Quercus JAVA PHP Interpreter”, which is a web application server , COMP ARABLE to Apache- T omcat ( https:// www.tomcat.org ); And that enables PHP developers to use existing JAVA libraries within their PHP code as well. “ ◦ “ I have implemented and tested a dynamic taint analysis using Firebug , and FirePHP . THIS taint analysis enables to warn developers about data and values that originate from outside the webserver , and / or also about values that emerge as results from operations that involve ”tainted values”; MEANING values that are considered not safe because they originate from the outside world of the Quercus web application server . “ ◦ “ T aking particular care of unsafe outside world data and values ( https://www.zenodo.org/record/ 8051293 ) allows developers to avoid web cyber–software security vulnerabilities attacks such as SQL injection, BUFFER–OVERFL OW attacks, format string vulnerabilities, etc.. “ É YEAR – 2024 IN our project Y E R I T H – W E B – PA G E S – G E N E R A T O R – 9.0 , we will need to instrument binaries of a running JAVA virtual machine; Most probably ”Debian–Linux OpenJDK Runtime Environment ” ( https:// docs. oracle.com ).

Par exemple Xavier (« Manager ») crée une alerte sur le pro- duit ”mangue” qui se déclenche dès que sa quantité en stock atteint 100 ; 1 message est généré et envoyé à l’utilisateur Jean (« Magasinier »). 5.2 Alertes sur une période de temps 1 période de temps est définie par 1 date de début de période, et 1 date de fin de période. 1 alerte sur une période de temps pour un produit est un mes- sage qui est généré et qui reste existant dans yerith-pgi-3.0 durant toute la durée de cette période de temps. Par exemple, un message d’alerte doit être envoyé a l’utilisateur Paul (« Caissier ») dès que la date du 05 Mai est atteinte afin que celui-ci applique un rabais de 20% sur chaque vente de yaourt ’trèsbon’ durant une période de 2 se- maines. 6 Le système de gestion de base–de– données ’MariaDB’ est utilisé comme système de gestion de base de données. ’MariaDB’ est très stable, très performant, et source–libre. Des copies exécutables de ’MariaDB’ peuvent être accessi- ble à très moindre coût (ex.: 0 ). 7 Conclusion Figure 3: La fenêtre de visualisation de stocks.

Quelques exemples d’entreprises commerciales au Cameroun et au monde : 1. MercedesBenz (RFA 1 ) 2. Walmart (États–Unis D’Amérique) 3. Cameroon Telecomunication (Camtel) (Cameroun) 4. Santa Lucia (Cameroun) 5. Supermarché DÔVV (Cameroun) 6. etc. 1. République Fédérale D’Allemagne. 11 DE 30 YERITH r&d YERITH–PGI–9.0: ESSAI DE PRODUCTIVITÉ ENTREPRENEURIALE 2.2 Sécurité Au Sein De L’entreprise NOS recherches et expériences sur le terrain nous démontre à suffisance que les éléments de sé- curités externes et internes à l’entreprise entrepreneuriale sont des suivants par ordre d’impor- tance : 1. ) LA SAINTE BIBLE : en effet, l’entrepreneur et / ou chef d’entreprise se doit de posséder 1 sainte BIBLE avant toute chose Puisque des paroles de Bonnes œuvres et vies proviennent de ce livre sacré qui est aussi le livre le plus ancien sur cette terre et UNIVERS humain. Nous recommandons 1 heure au minimum de lecture de versets bibliques par journée de vie ; Et non de TRAVAIL. Personnellement je peux conseiller par exemple des versets suivants : ◦ ”Esaïe 45 ” ◦ ”Sophonie 1 ” ◦ ”PSAUMES 140 ” ◦ ”PSAUMES 144 : 11 − 15 ” ◦ ”PSAUMES 23 ” ◦ ”HABACUC 3 : 15 − 19 ” ◦ etc. 12 DE 30 YERITH r&d YERITH–PGI–9.0: ESSAI DE PRODUCTIVITÉ ENTREPRENEURIALE 2.3 Définition De Performance La performance est une évaluation des activités d’une entreprise commerciale aux fins de justifier si cette dernière est rentable ou plus. Une entreprise commerciale est rentable lorsqu’elle produit des bénéfices (ou encore des sur- plus d’argents par rapport au Capital investit) . CAPITAL : : matériels physiques (aussi appelés IMMOBILISATIONS), et / ou sommes finan- cières investies pour faire fonctionner l’entreprise commerciale. 13 DE 30 YERITH r&d YERITH–PGI–9.0: ESSAI DE PRODUCTIVITÉ ENTREPRENEURIALE 2.4 Paramètres de Concurrence Des paramètres de concurrence sont des éléments qui influent sur l’attractivité d’ 1 entreprise com- merciale : 1 . 1 site internet (WWW : world wide web) AUX FINS DE DISTRIBUER SES INFORMATIONS COMMERCIALES ET DE SERVICES. 2 . 1 accessibilité facile (ou encore dégagée) 3 . 1 accessibilité propre 4 . des plaques publicitaires bien visibles 5 . des plaques publicitaires (ou encore rabats, ou promotions) bien visibles 6 . des prémisses (ou encore infrastructures) dégagées 7 . des prémisses (ou encore infrastructures) propres 8 . des prémisses (ou encore infrastructures) aérées (ou encore ventilées, ou bien climatisées) 9 . des prémisses (ou encore infrastructures) sentant bon 10 . des prémisses (ou encore infrastructures) avec des passages et/ou allées dégagés (ou en en- core non encombrés) 11 . des prix clairement affichés 12 . des prix à l’unité clairement affichés 13 . 1 très bonne sécurité des biens, des immobilisations, et des personnes sur les prémisses (ou encore infrastructures) 14 . 1 visibilité (ou encore publicité) sur le marché voulu 14 DE 30 YERITH r&d YERITH–PGI–9.0: ESSAI DE PRODUCTIVITÉ ENTREPRENEURIALE 2.5 Paramètres de Performance Figure 2.1 – Une image du PROGICIEL DE GESTION INTÉGRÉ (ERP en anglais) YERITH– ERP–PGI– 9.0 . Des paramètres de performance sont des éléments qui, lorsque maximaux, démontrent 1 rentabi- lité positive d’ 1 entreprise commerciale : 1 . 1 site internet (WWW : world wide web) AUX FINS DE DISTRIBUER SES INFORMATIONS COMMERCIALES ET DE SERVICES. 2 . 1 dissociation accrue et / ou élevée entre la famille de l’entrepreneur – investisseur, et ses af- faires commerciales (Exception faites au niveau des actionnaires ou du TRÈS–HAUT manage- ment) 3 . 1 visibilité maximale et informatisée sur des transactions commerciales de l’entreprise ; 4 . 1 Progiciel de gestion intégré simple et facile à ré-utiliser et / ou à entretenir, À TRÈS BAS COÛTS ; 15 DE 30 YERITH r&d YERITH–PGI–9.0: ESSAI DE PRODUCTIVITÉ ENTREPRENEURIALE 16 DE 30 YERITH r&d YERITH–PGI–9.0: ESSAI DE PRODUCTIVITÉ ENTREPRENEURIALE Chapitre 3 Processus D’ 1 Entreprise En Afrique Ce chapitre donne des canevas et / ou modèles (exemples) à partir desquels 1 or- ganisation entrepreneuriale peut développer ses processus de fonctionnements (en anglais aussi nommés "BUSINESS MODEL" ). 3.1 Visions et Objectifs D’ 1 Organisation Entrepreneu- riale Il est primordial et très important de définir 1 vision (ou encore 1 objectif idéal ; 1 but idéal à at- teindre dans le monde physique et / ou matériel avant de prendre 1 décision pour la création d’ 1 organisation entrepreneuriale [] (ex. : S.A.R.L, START–UP ; O.N.G., etc.). Exemple de vision d’ 1 organisation entrepreneuriale : — YERITH r&d : vulgariser et simplifier l’utilisation de l’outil informatique dans la gestion des organisations entrepreneuriales du monde moderne. — augmenter la consommation du choux vert vendu en boîte de conserve sans additifs chi- miques nocifs à la santé. — réduire les consommations de pétrole ; au profit de l’énergie éolienne. Le libellé d’ 1 vision et objectif entrepreneuriale devrait se limiter à 1 phrase au présent, à l’actif et non passif. 17 DE 30 YERITH r&d YERITH–PGI–9.0: ESSAI DE PRODUCTIVITÉ ENTREPRENEURIALE 3.2 Ressources de Fonctionnements 3.2.1 Ressources Humaines 3.2.1.1 Acquisition des Ressources Humaines 3.2.1.2 Salaires et Émoluments Figure 3.1 – Une image d’ 1 fenmêtre illustrative des groupes d’employés d’ 1 travailleur.
