PowerDesigner 与对象建模
Why Using UML?
• Visually define and communicate the structure and
behavior of an application
• Represent systems using Object-Oriented concepts
• Link OO concepts to executable code
2
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
3
UML Support in PowerDesigner
• PowerDesigner supports all nine UML diagrams
• PowerDesigner supports UML 1.4
• Future version of PowerDesigner will support UML 2.0
4
Use Case Diagram
• A Use Case Diagram describes the Actors, the Use Cases and
the interaction between the Actors and the Use Cases.

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

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

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

Statechart Diagram
• A Statechart Diagram is used to model the States and
Transitions of a Class
Intial
Play
Pause
9
Object Diagram
• An Object Diagram shows the relationships between
Object Instances
:Customer
id
= 101
name = "XiaoYun Wang"
:Order
id
=1
date = 3/25/2004
10
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.

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 represent EJBs,
Servlets, JSPs, ASPs and Web Services

EntityBean_CMP
GetProductPageJSP
GetProductList

12
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

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)
14
O/R Mapping Example
Use O/R mapping to generate SQL
Generate O/R mapping when
generating a PDM from an OOM
15
Java Support
• Provide wizards to automatically create EJBs, Servlets, JSPs,
Web Services
• Generate and reverse engineer Java code
• Generate collection management accessor functions
• Generate deployment descriptors
• Generate O/R mapping descriptor for WebLogic, WebSphere,
EAServer, JDO, JBoss (future)
• Generate project files for JBuilder and Eclipse
• Generate Ant script to compile, package and deploy J2EE
application
