Service Component Architecture (SCA) is a model to define
and implement SOA based solutions. This section details the IBM® implementation of SOA within WebSphere® ESB, and its associated
tooling, Integration DesignerWebSphere Integration Developer.
There are two defined sections within SCA:
- Service assembly, which details the service definitions and relationships
of the export, import, components and interfaces
- Service implementation, which details the construction of the
service definition and the transport of information through defined
protocols (web services, JMS, MQ, adapters).
In an SOA framework, high-level business components are exposed
as services. SCA provides a model for how the services in an SOA framework
are structured.
