Domain Specific languages .

domain-specific language (DSL) is a programming language or specification
language dedicated to a particular problem domain,
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
Traditional BPM approach
Collaboration Common Language
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.
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
BPMN 2.0 (business-oriented notation)
 Business Process Modeling Notation (BPMN) is a graphical representation for
specifying business processes in a business process model.
 The objective of BPMN is to support business process management for both technical users
and business users .
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.
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.

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
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.

Tasks
JPDL Elements
 jPDL has a number of process constructs
 start-state
 task-node
 Transition
 Decision
 Fork / Join
 process-state
 end-state
Process Deployment
Process Execution Cont.
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
