6. Problem

7. Business Logic Scattered Everywhere

8. Continuous Requirement Changes

9. Problem Dimensions

10. Business Process Management Domain Specific languages. BPM Definition. BPMN 2.0. Service Orchestration (PBEL).

11. Domain Specific languages. domain-specific language (DSL) is a programming language or specification language dedicated to a particular problem domain,programming languagespecification language

12. BPM Definition Business process: A procedure that describes how people and systems work together Business Process Management (BPM): Optimizing efficiency by automating,analyzing, describing and improving business processes

13. Traditional BPM approach

14. Collaboration Common Language

15. BPM Key Features Common Communication language. Graphically visualized process. Separation of concerns. Ease of Development and deploy. Ease of change and reuse Reduced development time/Time to Market.

16. Key Functions Workflow delivers the following functionality Automation of processes Routing and scheduling of activities Process visibility Process control through escalations and notifications Tracking of activities Collaboration of all parties involved Convergence of process and information Redesign of business processes

17. BPMN 2.0 (business-oriented notation) Business Process Modeling Notation (BPMN) is a graphical representation for specifying business processes in a business process model.graphical representationbusiness processesbusiness process model The objective of BPMN is to support business process management for both technical users and business users.

18. Service Orchestration (BPEL) Business Process Execution Language (BPEL) is a XML-based language used to define enterprise business processes within Web services. Service orchestration is to be seen in the context of an Enterprise Service Bus. An enterprise service bus is a central communication backbone on a corporate level. It integrates many diverse systems and it is based on XML technology.

19. Service Orchestration (BPEL ):Example Example Suppose you have services A, B and C on your enterprise service bus. Service orchestration is a graph based execution language for writing a new services as a function of existing services. E.g. A new service D can be written as a function of existing services A, B and C in an orchestration script.

20. jBPM Overview jBPM jBPM Architecture Keyword. jPDL Process Deployment Process Execution

21. Overview JBoss jBPM is a workflow, process automation, that enables coordination between disparate applications and services, resulting in the deployment of new revenue generating business processes

22. Architecture JBoss Enterprise Framework that delivers workflow, business process management (BPM) and service orchestration in a multi-process language platform and in a scalable and flexible product footprint.

32. Persistence Process and execution can be persisted Without persistence, the execution state of a process could not be stored and later retrieved. Standard Let Hibernate manage the connection or... Provide your connection to jBPM Combine your DB updates with jBPM In one transaction on the JDBC connection Enterprise Configure hibernate to participate in JTA transaction
