In changing world of e-commerce and internet based communication, business transactions and data flows play a key role in successful business management. It is vital for companies’ information systems to implement business transactions. The purpose of this work is to propose a model for outside business process’ implementation. Basic models’ steps are: business transaction specification, data structure and architectural solution selection. Communicative action loop is proposed for modeling business processes and XML is suggested as the best method for data exchange in an internet based environment. Deploying three-tier architecture completes the models’ steps for successful business information system implementation. In this work we propose a multipurpose tool – DAO (Data Abstraction Object), based on PHP to control, manage and save XML document data. A PHP alternative way – Java Servlet technology is also discussed for using Java tools for XML processing and database connection. At the end of the work an example information system is implemented following the steps described above.

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.

Pragmatically motivated communicative action loop (CAL) is proposed for modeling business transactions and designing database transactions. Using parameters of the communicative action loops, activity model can be adapted to particular objective area. Selected parameters are utilizable in formation of database transactions that are oriented in modification of states of objects of activity. Performed database transactions are registered to query register in order to make a database rollback when business transactions are canceled. Database transactions are synchronized between two replicated databases.
