IT industry all time is looking for ways to improve software development productivity as well as the quality and longevity of the software that it creates. OMG announced Model Driven Architecture as its strategic direction. It is software development methodology that provides new viewpoint in software development process. The modeling of problem domain and model transformation are key elements of MDA architecture and they are analyzed in this work using OMG specifications and other resources. The purpose of this work is to evaluate benefits of MDA framework in software development process. The new MDA framework is developed according to the results of MDA architecture analysis. Experimental usage of new MDA framework concentrates on productivity of software development process, automation of repeated tasks and required skill set of application developers.

The recent version of UML 2.0 (in year 2006) specifies activities and actions, which allow describing low level behavior of software system being modeled, in implementation independent fashion. This work analyzes suitability of UML 2.0 activities and actions for generating full program code (or as many as possible). It also proposes a method for generating program code from UML 2.0 activities and actions, which consists of a way to express UML activities with concurrently executing actions in a sequential execution scenario and a way to determine the exact code template (among the few possible) for UML activity elements based on identifying the particular context of element in question.

Šiame darbe analizuojama MDE programų inžinerijos metodai, o taip pat OMG MDA ir Microsoft DSL Tools. MS DSL Tools - tai galingas priedas prie MS Visual Studio 2005, skirtas taikymo srities kalbų metamodelių kūrimui ir grafinių aplinkų darbui su jomis generavimui. Taip pat galima sukurti tekstinų šabloną, kuris gali transformuoti duotą modelį į programinį kodą. Darbe aprašomas sukurtas modeliavimo kalbos metamodelis. taip pat aprašoma tekstinių šablonų kalba, skirta modelių trasformacijom kurti. / This paper analyses MDE approach to software engineering as well as OMG’s MDA and Microsoft DSL Tools. MS DSL Tools are a powerful addition to MS Visual Studio 2005 for creating your own Domain Specific Language metamodels and generating IDEs for working with it. Then you can make a text template to transform your model directly into code. The work describes developed aggregate modeling language metamodel. It also explains text template language for model transformations. The research also includes analysis of the possibility to use model transformations to generate code for data acquisition form database.

Daugeliui įmonių ar organizacijų reikalingos informacinės sistemos, skirtos valdytį jų procesus duomenis. Darbe analizuojamos verslo procesų, transakcijų modeliavimo galimybės, technologijos, standartai: RUP, UML, XML (XMI), MERODE, R. Gusto, WAE, BPMN, MDA, Agile. Deliau analizuojamas verslo procesų modelis ir jo plėtinys BPMN. Pateikti pasiųlymai notacijos išplėtimui duomenų objektais, modelių ir elementų interpretacija modeliuojant o modelius panaudojant kodo generavime. Sudarytas ir ištestuotas pilnai funkcionuojančio ir dalykinę sritį atitinkančio kodo generavimo algoritmas. / In nowadays a lot of business companies and organizations are using information systems. This paper analyses business transactions, tools and technologies for transactions and process modelling of information and enterprise systems. Analyzed popular technologies like UML and its extensions, RUP, XMI, MDA. Familiarized with MERODE and Agile methods. More closely analyzed BPMN notation and its possibilities for code generation. BPMN notation augment with data objects for better code generation solutions. It also gives better understanding of data flows and influence of business process and transactions. Defined process and transactions modelling strategy which allows better code generations solution too. Made-up, practically materialized ant tested code generation algorithm.

Programinio kodo generavimo iš veiklos taisyklių modelių sritis iki šiol yra menkai ištirta ir tai neigiamai veikia veiklos taisyklių koncepcijos plėtrą. Nagrinėjama kodo generavimo iš grafinių IS (informacinių sistemų) reikalavimus atspindinčių modelių problema. Pristatomas modifikuotu Roso metodu grindžiamo veiklos taisyklių modeliavimo IS projektavimo stadijoje metodo tyrimas, siekiant sukurti adekvačią programinio kodo generavimo iš taisyklių diagramų metodiką. / One of the reasons for a relatively slow growth of the business rules approach could be the lack of developments in the field of program code generation from the business rules models. During this work methods for code generation from IS requirements models are analysed. The focus is placed on a modified Ross method based rules modelling method aiming to create an adequate code generation methodology.
