Component-Based Software Engineering

Operating systems provide:

an abstraction of the underlying handware

an execution environment

basic services for applications

Compoment models define standards for:
Interface, Naming, Meta data, Interoperability, Customization, Composition, Evolution support, Packaging and deployment.

Component model implementation provides:

run-time environment

basic services

horizontal services that are useful across multile domains

vertical services providing functionality for a particular domain for software compoments

The component-based software lifecycle:
CSLC is the life cycle process for a software component with an emphasis on business rules, business process modeling, design, construction, continuous testing, deployment, evolution and subsequent reuse and maintenance.
