Component-based ​

Component-based architecture focus on reusability and separation of concerns principle.

Component ​

  • A building block from a system
  • A concrete implementation in the code, not an abstract concept
  • Deployable and replaceable
  • Component can be grouped together to form packages

Interface ​

To communication with each other, component provide interfaces which act as contracts.

  • An interface’s implementation shall do what its methods says it does
  • An interface's implementation shall do no harm
  • If an implementation is unable to perform its responsibilities, it shall notify its caller
