Component-based software engineering (CBSE) (also known as Component-Based Development (CBD) or Software Componentry) is a branch of the
software engineering discipline, with emphasis on
decomposition of the engineered systems into
functional or
logical components with well-defined interfaces used for communication across the
components. Components are considered to be a higher level of
abstraction than objects and as such they do not share state and communicate by exchanging messages carrying data.
