This subscription version of Visio supports UML shapes conforming to the UML 2.5 specification while also providing you the flexibility to use them as needed in your diagrams. To model the applications of an application.In Visio Plan 2 and Visio 2019, you can start with a blank UML template or (in some cases) modify a UML starter diagram.The component diagram can be used for the followings: are first needed to be organized before the implementation. The components, such as libraries, files, executables, etc. It represents the physical components of a system, or we can say it portrays the organization of the components inside a system. The component diagram is a special purpose diagram, which is used to visualize the static implementation view of a system. To clarify the important points, notes can be incorporated.Ī component diagram for an online shopping system is given below: Where to use Component Diagrams?.Before producing the required tools, a mental layout is to be made.Using a meaningful name to ascertain the component for which the diagram is about to be drawn.What is the relationship between the artifacts?įollowing are some points that are needed to be kept in mind after the artifacts are identified:.What is the application of relevant libraries and artifacts?.It plays an essential role in implementing applications efficiently.įollowing are some artifacts that are needed to be identified before drawing a component diagram: Once the system is designed employing different UML diagrams, and the artifacts are prepared, the component diagram is used to get an idea of implementation. It is utilized in the implementation phase of any application. The main purpose of a component diagram is different from that of other diagrams. The component diagram is helpful in representing the physical aspects of a system, which are files, executables, libraries, etc. To represent the component organization of the system.To divide a single system into multiple components according to the functionality.Following are some reasons, which tells when to use component diagram: It describes how individual components can together form a single system. It is helpful in visualizing the structure and the organization of a system. It represents various physical components of a system at runtime. It envisions the links between several connections.It portrays the components of a system at the runtime.The system cannot be visualized by any individual component, but it can be by the collection of components.įollowing are some reasons for the requirement of the component diagram: In UML, the component diagram portrays the behavior and organization of components at any instant of time. It is used to depict the functionality and behavior of all the components present in the system, unlike other diagrams that are used to represent the architecture of the system, working of a system, or simply the system itself. The component diagrams have remarkable importance. It depicts the relationships and organization of components.It constructs the executable by incorporating forward and reverse engineering.It envisions each component of a system.The main purpose of the component diagram are enlisted below: The collection of component diagrams represents a whole system. The component diagram also describes the static view of a system, which includes the organization of components at a particular instant. The components can be a library, packages, files, etc. It visualizes the physical components inside the system. It describes all the individual components that are used to make the functionalities, but not the functionalities of the system. Since it is a special kind of a UML diagram, it holds distinct purposes. It is like a black box whose behavior is explained by the provided and required interfaces. The implementation details of a component are hidden, and it necessitates an interface to execute a function. A component is a single unit of the system, which is replaceable and executable. It helps in forming an executable system. It visualizes the relationships as well as the organization between the components present in the system. It models the physical view of a system such as executables, files, libraries, etc. A component diagram is used to break down a large object-oriented system into the smaller components, so as to make them more manageable.
