What is Component Diagram?

A component diagram depicts how components are wired together to form larger components or software systems. They are used to illustrate the structure of arbitrarily complex systems. A component is a modular part of a computer software system. It represents a group of related classes and other elements that work together within a self-contained logical structure in order to provide some aspect of the system's functionality. A component diagram can be used in the early stages of system design to establish the overall architecture of the system.

Why Component Diagram?

In component-based development facilitates the concept such as build application by components assembly. Component diagram help us to form component based system architecture:

  • Component diagrams offer architects a natural format to begin modeling a solution.
  • Component diagrams allow an architect to verify that a system's required functionality is being implemented by components, thus ensuring that the eventual system will be acceptable.
  • Developers find the component diagram useful because it provides them with a high-level, architectural view of the system.
