上海交通大学：《面向对象分析与设计 Object Oriented Analysis and Design》课程教学资源（PPT课件讲稿）17 Model Driven Development

 Map persistent design classes to the data model  Distribute class behavior to the database

 Goals ▪ Loose coupling ▪ Portability, plug-and-play compatibility ▪ Insulation from change ▪ Independent evolution  Strong Suggestions ▪ Do not expose details, only interfaces ▪ Depend only on other interfaces

 Describe interaction among design objects  Simplify sequence diagrams using subsystems  Describe persistence-related behavior  Refine the flow of events description  Unify classes and subsystems

 Identify classes and subsystems  Update the organization of the Design Model  Describe Distribution  Runtime Architecture

 Supplement the Use-Case Description  For each Use-Case Realization ▪ Find Classes from Use-Case Behavior ▪ Distribute Use-Case Behavior to Classes  For each resulting analysis class ▪ Describe Responsibilities ▪ Describe Attributes and Associations ▪ Qualify Analysis Mechanisms  Unify Analysis Classes

 Key Concepts  Define the High-Level Organization of Subsystems  Identify Analysis mechanisms  Identify Key Abstractions  Create Use-Case Realizations
