2. Outline Components Component Diagrams System And Models

3. Components DEF: A physical & replaceable part of a system that conforms to and provides the realization of a set of interfaces Physical : A. live in a world of bits B. reside on physical node can be executed directly or ‘indirectly’ participate in an executing system Replaceable : Components can be replaced in system by adding new ones without rebuilding system

4. Components realization of a set of interface: Component provide as a service to other components Interface: A set of operation that are used to specify a service of a class or component 比較 ComponentClassInterface Operationthrough interface to access through method to access only method name,no implement operation AttributeNot includeincludeNot include

5. Components ClassComponent 表現方式 Logical abstraction Physical thing 存在方式 A way of thinkPhysical package 存取方式 methodinterface

6. Components Image.java Component. java ImageObserver interface dependencyrealization Iconic form: P.348

7. Kinds of Components Components Deployment components Work product components Execution components Standard Elements in UML Executable Library Table File Document

8. Common Modeling techniques 1. 從技術方面, 修正與管理方面, Reuse 方面, 確定系統中實體的每一個部分 2. 利用適當的 UML 元素, 把 executable 和 libraries model 成 component 3.Model 重要的 interface : 系統的接合點 4. 找出 component 相依的關係 使其可 visualize Components

9. DEF: Shows a set of components and their relationship Component Diagrams Find.exe Find.html Index.html Dbacs.dll Nateng.dll executable page library component

10. Common uses Component Diagrams Model source code Model an Executable Release Model a Physical Database Model Adaptable System

11. Systems and Models System A collection of subsystem, a set of element Organized to accomplish a purpose and describe by a set of models Model: A simplification of reality—a abstraction of a system –created in order to understand the system View A projection of model, which is seen from one perspective or vantage point and omit entities that are not relevant to this perspective

12. Systems and Models > Retail Enterprise System > In store Management subsystem > Warehouse Management subsystem > Customer Service subsystem subsystem system
