Libraries and other artifacts relevant to the application.Īfter identifying the artifacts, the following points need to be kept in mind. A well-prepared component diagram is also important for other aspects such as application performance, maintenance, etc.īefore drawing a component diagram, the following artifacts are to be identified clearly − This diagram is very important as without it the application cannot be implemented efficiently. Initially, the system is designed using different UML diagrams and then when the artifacts are ready, component diagrams are used to get an idea of the implementation. However, it is prepared well in advance to visualize the implementation details. Component diagrams are used during the implementation phase of an application. The purpose of this diagram is different. Includes files, executables, libraries, etc The purpose of the component diagram can be summarized as −Ĭonstruct executables by using forward and reverse engineering.ĭescribe the organization and relationships of the components.Ĭomponent diagrams are used to describe the physical artifacts of a system. Static implementation represents the organization of the components at a particular moment.Ī single component diagram cannot represent the entire system but a collection of These components are libraries, packages, files, etc.Ĭomponent diagrams can also be described as a static implementation view of a system. Thus from that point of view, component diagrams are used to visualize the physical components in a system. It does not describe the functionality of the system but it describes the components used to make those functionalities. The purpose is also different from all other diagrams discussed so far. Purpose of Component DiagramsĬomponent diagram is a special kind of diagram in UML.
These diagrams are also used to make executable systems. Now the question is, what are these physical aspects? Physical aspects are the elements such as executables, libraries, files,Ĭomponent diagrams are used to visualize the organization and relationships among components in a system. Component diagrams are used to model the physical aspects of a system. Component diagrams are different in terms of nature and behavior.
