Service Component Architecture (SCA)

"A set of specifications which describe a model for building applications and systems using a Service-Oriented Architecture. SCA extends and complements prior approaches to implementing services, and SCA builds on open standards such as Web services."


  • Component - general term for a configured implementation of an SCA application
  • Composite - larger structure composed of several components
  • SCDL - Service Component Definition Language used for composite configuration files
  • Domain - container for components and composites
  • Service - exposes a components business logic
  • Reference - used by a component to indicate the services it relies on
  • Property - an instantiated component value which can be read from the SCDL configuration
  • Binding - specifies how components communicate with other software

Supported by BEA, IBM, Oracle, SAP AG, Red Hat, Sun, TIBCO and others.
