Definition of SOA SOA - a software architecture that defines the use of software services to support business processes and software users. The central concept in SOA - a service

18-19 March 2011, Gabrovo, Project No: BG 051 PO /13 Подкрепа на творческото развитие на докторанти……..” Institute of Information and Communication Technologies – Bulgarian Academy of Sciences The ideas of SOA are not new. - SOA incorporates concepts used by Object-Oriented development, Component-Based Design, and Enterprise Application Integration technology to build architectural integrated solutions. - Services are the main parts of SOA distributed information systems. They can be invoked from internal or external services and can be bundled to provide more complex functionality. -SOA makes the development of flexible distributed information systems by exploiting reusable components as info services.

Web services Web services utilize XML-based format for building explicit descriptions of service interfaces. The combination of Web services solves integration problems with heterogeneous IT systems. Web services  realized on different software technologies: XML, SOAP, HTTP. Web services  independent of the underlying technologies Web services  support different methods of communications (asynchronous and synchronous messaging.

Evolution of business process management  Two languages are central for the specification and execution of all workflows  Choreography languages: modelling  Orchestration focuses on the behaviour of a single business entity: execution

18-19 March 2011, Gabrovo, Project No: BG 051 PO /13 Подкрепа на творческото развитие на докторанти……..” Institute of Information and Communication Technologies – Bulgarian Academy of Sciences  Choreography is concerned with global, multiparty, peer-to-peer collaborations where business entities interact in coordinated fashion regardless of any programming model or supporting platform used. Choreography languages: BPSS (Business Process Specification Schema), WS-CDL (Web Services Choreography Description Languages)  Choreography languages cannot be directly executed and have to be translated to an orchestration language in order to be executed.  Orchestration executes the workflow model and focuses on the behaviour of a single business entity.  Orchestration languages: BPML (Business Process Modeling Language), BPEL (Business Process Execution Language), XPDL (XML Process Definition Language), BPELJ (BPEL for Java ), jPDL (Java Process Definition Language ) are executable languages and define a runtime environment for their execution.
