Component-based software engineering

Component-based software engineering (CBSE), also called component-based development (CBD), is a style of software engineering that aims to construct a software system from components that are loosely-coupled and reusable. This emphasizes the separation of concerns among components.[1][2]

Considerations[edit]

An example of two components in UML: Checkout processes a customer's order, which requires the other one to bill the credit card.

For large-scale systems developed by large teams, a disciplined culture and process is required to achieve the benefits of CBSE.[3] Third-party components are often utilized in large systems.

The system can be designed visually with the Unified Modeling Language (UML). Each component is shown as a rectangle, and an interface is shown as a lollipop to indicate a provided interface and as a socket to indicate consumption of an interface.

Component-based usability testing is for components that interact with the end user.
