  1. The Joint UML for EDOC Submission ad/2001-06-09 Submitters: CBOP, Data Access Technologies, DSTC, EDS, Fujitsu, IBM, Iona Technologies, OPEN-IT, Sun Microsystems, Unisys Supporting companies: Hitachi, Netaccount, SINTEF …

  2. Agenda • Introduction to UML for EDOC • Vision and Rationale • Submission structure, RFP Requirements • Platform Independent Modeling - ECA • CCA Profile • Entities Profile • Events Profile • Business Process Profile • Relationships Profile • Patterns • Platform Specific Modeling • EJB, FCM, MOF • Technology Mappings • Summary, RFP Requirements - Discussion

  3. EDOC Vision • Simplify the development of component based Enterprise (EDOC) systems by means of a modeling framework, based on UML 1.4 and conforming to the OMG Model Driven Architecture. • Provide a platform independent, recursive collaboration based modeling approach that can be used at different levels of granularity and different degrees of coupling, for both business and systems modeling.

  4. EDOC Key RFP Requirements • Modelling framework for enterprise distributed object computing systems: • Based on UML 1.4 • System operation directly relatable to business processes • Models driven by business requirements • Mappable to different platforms (incl. CORBA ) • Specifically, support modelling of: • Business entities • Business processes • Business rules • Business events.

  5. Submission Structure

  6. Using RM-ODP viewpoints Enterprise viewpoint (CCA, Business Processes, Entities, Relationships, Events) Part I: ECA Information viewpoint Computational viewpoint Computational viewpoint (Entities, Events, Relationships) (CCA, Entities, Events) (CCA, Entities, Events) Part II: Part II: Engineering viewpoint Engineering viewpoint ECA to technology (Technology abstraction: FCM) (Technology abstraction: FCM) mappings mappings Part I:Technology Part I:Technology Specific Models Specific Models Technology viewpoint Technology viewpoint (UML for J2EE/EJB/JMS, CORBA 3/CCM, COM, SOAP, ebXML) (UML for J2EE/EJB/JMS, CORBA 3/CCM, COM, SOAP, ebXML) Part I: Patterns - applied to all viewpoints

  7. Four general categories of ProcessComponent

  8. The Internet Computing Model • Collaboration of independent entities • Document exchange over internet technologies • Large grain interactions, not “method calls” • No required infrastructure * • Long lived business processes • Business transactions • Not technical transactions Portals Business Party Business Party

  9. “Pattern” for the MDA Platform Independent Models Technology mappings ECA Events Entities Process CCA Relationships Integration -viewpoints Patterns Platform Independent Models Platform Specific Models FCM CORBA COM EJB MOM ebXML etc

  10. Platform Independent Modeling The Enterprise Collaboration Architecture

  11. CCA Component Collaboration Architecture Collaborative process component specification for ECA

  12. The Marketplace Example Physical Delivery Order Conformation Shipped Process Complete Mechanics Are Us Buyer Acme Industries Seller Status Ship Req Shipped Delivered GetItThere Freight Shipper

  13. The Seller’s Detail Order Processing Shipping Receivables Event Order Conformation Shipped Ship Req Shipped Delivered

  14. The Buyer’s Detail Supplier Evaluation Order Receive Goods Process DataFlow Process DataFlow Order Conformation Shipped Ship Req Shipped Delivered

  15. Specification of CCA Structure + Composition + Choreography

  16. Parts of a CCA Specification • Structure of process components and protocols • Process components, ports, protocols and documents • Class Diagram or CCA Notation • Composition of process components • How components are used to specify components • Collaboration diagram or CCA Notation • Choreography • Ordering of flows and protocols in and between process components • Activity Diagram

  17. Process Component • A CCA Process Component defines a configurable behavioral unit that can be composed in a particular way • They can be logical or physical, concrete or abstract • They can represent anything from a business partner in a B2B exchange to a fine-grain computation • Process Components can be used to compose other process components, recursively • CCA is intended to be specialized, as a core architecture for process, entities and events at multiple levels of granularity • CCA is compatible with the ebXML Business Process Specification Schema which specifies B2B collaborations • Extends real-time capsule model

  18. The Community Process • Identify a “community process”, the roles and interactions • Using CCA Notation

  19. Component structure Component structure Defines the “outside” Contract of a component

  20. Meta Model for Structure Key Point: Process Components have ports That either initiate or respond To a protocol or flow

  21. Protocol Example • Specification of a protocol

  22. Meta Model for Protocol MetaModel Model

  23. Choreography of Protocol

  24. Use standard interface notation Are a subtype of “Protocol” in the MetaModel Allow modeling of and integration with classical and/or existing objects Object Interfaces

  25. Composition Use of an interface Composition defines the “inside” of a component

  26. Composition MetaModel

  27. Properties • Properties make process components configurable • They can be reset when a component is used – in a composition or at deployment time

  28. ECA Entity Profile The model of things

  29. Sample Information Model

  30. MetaModel for Information Model

  31. Entities are added to manage entity data Entity Roles are managers that provides a view of the same identity in another context The Entities have ports for managing and accessing the entities Non-entities which are owned by (aggregate into) an entity are managed by the entity Adding Entities

  32. Entity Meta Model

  33. ECA Business Events The model of when…

  34. Event Based Business Processes Business Rules Business Services Business Process Business Events Business Actions Business Entity

  35. Event Based Business Processes Business Rules Event Notification Business Process Business Actions Business Events Business Entity Business Rules Business Process Business Events Business Actions Business Entity

  38. PubSub Package

  39. Event Package

  40. Putting it all together Business Rules Business Process Business Actions Business Events Business Entity

  41. Event Example

  42. Summary of Advantages • Recursive decomposition & assembly • Trace ability • Automating the development process • Loose coupling • Technology Independence • Enabling a business component marketplace • Simplicity through abstraction

  43. Business Process Profile how things are coordinated

  44. Business Processes • Specialize CCA • Activity-centric view of a Process • Express • Complex temporal and data dependencies between business activities • Iteration of activities • Alternative required Inputs and Outputs of activities • Roles related to performers, artifacts and responsible parties for activities

  45. The Business Process Concepts CT C A PR1 RP B AR PR2

  46. ProcessComponent Specialization • CompoundTask is a special ProcessComponent • Its Ports represent the type of an Activity • Its Composition arranges Activities in a dependency graph • Activity is a special ComponentUsage • Its MultiPort usages contain ProcessPortConnectors (ProcessFlowPort usages) • DataFlows between these Connectors express dependencies between Activities

  47. Metamodel for BP Components CT C A PR1 RP B Activity AR PR2

  48. BusinessProcess and BusinessProcessEntity • A BusinessProcess • Exposes arbitrary Ports (outside) • which define interfaces, operations, events for composition using CCA • Its Composition (inside) is restricted to containing Activities and DataFlows • A BusinessProcessEntity • Is a BusinessProcess whose instances are uniquely identifiable

  49. Port Types and Semantics • ProcessMultiPorts specialize CCA Multiports • They act as correlators for data from many sources • May be synchronous (required before starting an Activity) • or asynchronous (accepted by Activity during execution) • ProcessFlowPorts specialize CCA FlowPorts • Multiplicity indicates how many values are required to enable containing Multiport • 3 concrete kinds of ProcessMultiPort • InputGroup – alternative data sets required to begin an Activity • OutputGroup – alternative Activity result data sets • ExceptionGroup – abnormal Activity results
