Approaches to transformation of process description to BPEL
Císař, Daniel ; Gála, Libor (advisor) ; Selčan, Vladimír (referee)
In this work, I dealt with the field of Business Process Managent and Service Oriented Architecture. First I tried a comprehensive conceptual view of both through the definition of important principles. In BPM as a disciline I identified "life-cycle" as the most important principle for process optimization tools. For service-oriented architecture, I had to reduce the view to important principles related to composition of services. An important starting point in my work are the definitions of processes and services and their roles in BPM systems. It is a simplified view that helps connect modeled processes to Web services. Web services and orchestration is the most popular and most common usage of the service-oriented architecture. Composition is another important building block of SOA and is the basis for more realistic goals of SOA, such as greater enterprise agility, more efficient utilization of resources in the enterprise, etc. BPM discipline combines multiple elements and as it is typicaly multidisciplinary it combines process management and optimization through tools. These tools historically perform their roles well, but companies are now in a very competitive linked environment and must to behave differently. In my work I have stated firstly why would these areas could be beneficial to each other. The next part focused, what is the relationship with the life-cycle process for BPM and how it fits into the life-cycle services in SOA. Finally, I analyzed the current state mapping of BPMN, the most common notation for expressing processes in BPM, to BPEL. BPEL describes a process, but it is expressed as a programmatic sequential process, which is also executed in digital form. At work I have examined the role of the new version of the BPMN notation 2.0.
