Facilitates efficient cooperation between groups, each doing what they do best. Facilitates code re-use and rapid comparison of different methods, etc. CBSE = Component-Based Software Engineering Component technology is basically “plug and play” technology (think of “plugins”) With components, clean separation of functionality is mandatory vs. sending data to multiple components simultaneously). Allows for multicasting calls that do not need return values (i.

Have potential to encapsulate parallelism better. Provide a clear specification of inputs needed from other components in the system. Can be customized with configuration parameters when application is built.

Can have multiple different interfaces and can have state. Can easily be moved to a remote location (different address space) without recompiling other parts of the application (via RMI/RPC support). Can be replaced, added to or deleted from an app. Subroutine Programming Can be written in different languages and still communicate. Component Technology Advantages of Component vs.
