4. 为什么要使用模型驱动开发工具

5. 为什么要使用模型驱动开发工具? Would You Build a House Without aBlueprint? • The Architect will do the first high level drawings to validate the concept with its client He will then make a detailed plan for the Builders • The Builders will take this blueprint and optimize it based on technical constraints

6. 开发软件的问题 • How to improve application quality, reduce development time and ease maintenance? • How to model business-driven application? • How to design applications in such way that they are easy to change? • Different techniques (E/R, UML, BP Modeling) have forced corporations to buy different tools, raising communication and co-ordination issues • Lack of central place to store and manage models

7. 模型驱动开发工具 • To improve application quality, reduce development time and ease maintenance • Use Modeling tool to analyze and design the applications • Use Modeling tool to generate the specification • Use code generators to generate the database, the application code • Use repository to store models and manage versions • To model business-driven application and allow applications to be easilly changed • Use Business Process Model, UML and Data Model together

26. PowerDesigner 与业务流程建模

27. Why Using Business Process Modeling? • It is not technical; it is easy to use. • Business users can use it to: • Describe the current business processes • Define the future business processes • Optimize business processes • Improve ROI • BPM can be used to design and generate BPM and workflow standards (ebXML, BPML, XPDL, …) • BPM can be used to design and generate Web Services orchestration standards (BPEL4WS, …)

28. Why We Use BPM instead of UML? • BPM tool is essentially for business users. It should be very easy to use. • UML is more technical and more complex. It is good for designing applications but not for describing business processes. • We offer well adapted tools for different usages instead of forcing all users to use UML.

29. Business Process Model Concepts • Predefined Symbols • Start • End • Process • Flow • Decision • Synchronization • Organization Unit • Resource • Service provider, interface, operation • Data

30. Example of a High-Level BPM • Describe system architecture

31. Example of a Detailed BPM Swimlane

33. Support Simuation (new in V10) • Use simulation to optimize business processes (costs, delay, resources) • Define Simul8 specific properties • Generate Simul8 models • Reverse engineer Simul8 properties

34. Support Service-Oriented Architecture (SOA) • Support Service provider, Service interface and operation • Import WSDL, UDDI browser • Assign service operation to process • Web Services assembling • Design, generate, reverse engineer BPEL4WS

35. Generate Sybase Integration Orchestrator Model • Define IO specific Business Process Model in PowerDesigner • Generate IO model • Refine IO model

36. Support ebXML BPSS • Design, generate and reverse engineer ebXML Business Process Specification Schema (BPSS) • Generate Private Process Options for Process Server • Process Server can import the generated ebXML BPSS.

37. PowerDesigner 与对象建模

38. Why UsingUML? • Visually define and communicate the structure and behavior of an application • Represent systems using Object-Oriented concepts • Link OO concepts to executable code

39. Brief Overview of UML • UML is defined by OMG. • UML consists of 9 diagrams: • Static • Class diagram • Object diagram • Dynamic • Use Case diagram • Sequence diagram • Statechart diagram • Collaboration diagram • Activity diagram • Implementation • Component diagram • Deployment diagram

40. UML Support in PowerDesigner • PowerDesigner supports all nine UML diagrams • PowerDesigner supports UML 1.4 • Future version of PowerDesigner will support UML 2.0

41. Use Case Diagram • A Use Case Diagram describes the Actors, the Use Cases and the interaction between the Actors and the Use Cases.

42. Collaboration Diagram • A Collaboration Diagram describes the interaction between objects (instance of classes) by exchanging messages. • Collaboration Diagram can be used to identify classes and operations

43. Sequence Diagram • A Sequence Diagram describes the interaction between objects and how the messages are exchanged over time. • Sequence Diagram is used to identify classes and operations

44. Activity Diagram • An Activity Diagram describes the logic and the control flow of a Use Case, an Operation or another Activity.

45. Statechart Diagram • A Statechart Diagram is used to model the States and Transitions of a Class

46. Object Diagram • An Object Diagram shows the relationships between Object Instances

47. Class Diagram • A Class Diagram defines the Classes, Interfaces, Attributes, Operations, Relationships, Inheritances, … • A Class Diagram can be used to define persistent objects, control objects and user-interface objects. • A Class Diagram can be used to generate the Physical Data Model and the application implementation code.

48. Component Diagram • A Component Diagram can be used to define the components you need to create for an application • A Component can use Classes, Interfaces • PowerDesigner uses Components to representEJBs, Servlets, JSPs, ASPs and Web Services

49. Deployment Diagram • A Deployment Diagram is used to define the deployment architecture • Deployment Diagram shows the Nodes (machines, servers), the Component Instances deployed in a Node and the Links between Nodes

50. Object/Relational (O/R) Mapping • Generate a Class Diagram from a Physical Data Model with O/R mapping • Generate a Physical Data Model from a Class Diagram with O/R mapping • Manually define complex O/R mapping • Generate select, insert, update, delete SQL statements • Use O/R mapping to generate EJB CMP (WebLogic, WebSphere, EAServer), JDO, Cocobase, .NET (future)
