An application component represents an encapsulation of application functionality aligned to implementation structure, which is modular and replaceable. An application component is a self-contained unit. As such, it is independently deployable, re-usable, and replaceable. (ArchiMate® Standard, Version 3.1, The Open Group)

Solution Building Blocks, or more precisely an implementation of the technical aspects of SBB, is represented as an Application Component in the DE4A architecture.


DE4A solution overview
