Component and Deployment Diagrams - Brief Overview

1. Component And Deployment Diagram Presented by Rajiv Kumar V, 13M510, NITH.

2. INTRODUCTION UML diagram classification: Static Use case diagram, Class diagram Dynamic State diagram, Activity diagram, Sequence diagram, Collaboration diagram Implementation Component diagram, Deployment diagram Implementation diagrams describe the different elements required for implementing a system

3. COMPONENT DIAGRAM Models the physical implementation of the software (file resources) Models the high-level software components, and their interfaces Dependencies are designed such that they can be treated as independently as possible Components to use with Component Diagram are: Components required to run the system(library file, etc.) Source code file, and data file Executable file (.exe )

4. COMPONENT DIAGRAM (contd…) Component is an Autonomous unit Modular Encapsulated Hidden internals and inaccessible One or more interfaces Well defined interface lets to access the component’s operations Component and subsystems can be flexibly reused and replaced

5. Elements of Component Diagram Component Stereotype << executable >>: executable file (.exe) << library >>: references resources (.dll) << file >>: text file, source code file, etc. << table >>: database file, table file, etc. << document >>: document file, web page file, etc .

6. Elements of Component Component Interface Component dependencies

7. Elements(contd…) Interface may also be shown using a rectangle symbol with a keyword <<interface>> preceding the name Services that the component expects from its environment is modeled using a socket multiple components that require or provide a particular interface

8. Component Diagram (An example)

9. Deployment Diagram Describes the physical resources of the system (hardware). Software runs on nodes Nodes can be PC Client, Storage device, Server. etc . Shows physical arrangement of run-time computational resources such as computer and its interconnections.

10. Elements of Deployment diagram Node

11. Elements of Deployment diagram Association Component and nodes

12. Deployment diagram (An Example)

13. CONCLUSION Components Physical and replaceable part of the system that conforms to and provides the realization of a set of interfaces e.g.: COM+ components, Java Beans, … source code files Documents Nodes Describes the physical resources and the components it hold
