Component Diagram Example: Online Shop

Description:

This is a simple component diagram that shows the components and the interfaces that required and provided. The port symbols attached to the components' border are used as a connecting point between a component and an interface it requires or provides.

What is Component Diagram?

Component diagrams are used in modeling the physical aspects of object-oriented systems which shows the organization and dependencies among a set of components. Component diagrams are used to model the static implementation view of a system. They are essentially class diagrams that focus on a system's components. Component diagrams are used for visualizing, specifying, and documenting component based systems and also for constructing executable systems through forward and reverse engineering. Component diagrams commonly contain Components, Interfaces and Dependency, generalization, association, and realization relationships. It may also contain notes and constraints. Graphically, a Component diagram is a collection of vertices and arcs.

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.
