Component-based software engineering is a branch

of software engineering that emphasizes the

separation of concerns in respect of the wide-ranging functionality available throughout a

given software system.

http://en.wikipedia.org/wiki/Component-based_software_engineering

It is a reuse-based approach to defining,

implementing and composing loosely coupled independent components into systems.

This practice aims to bring about an equally wide-ranging degree of

benefits in both the short-term and the

long-term for the software itself and for

organizations that sponsor such software.

Sorry this is *NO hot shit*!

The idea first became prominent with

Douglas McIlroy at the NATO conference on software

engineering in Garmisch, Germany,

1968
