Service Component Architecture

Service Component Architecture (SCA) is a software technology designed to provide a model for applications that follow service-oriented architecture principles. The technology, created by major software vendors, including IBM, Oracle Corporation and TIBCO Software, encompasses a wide range of technologies and as such is specified in independent specifications to maintain programming language and application environment neutrality. Many times it uses an enterprise service bus (ESB).

In addition to the partners, the SCA community had some formal supporters. On March 21, 2007, the OSOA Collaboration released the first version of specification. The specifications said that an application designed with SCA should have: SCA, therefore, was promoted to offer flexibility for composite applications, flexibly incorporating reusable components in an SOA programming style. Marketing firm Gartner Group published a short brief that promoted the SCA and its included technology of Service Data Objects (SDO) in December 2005 .
