SOA specification is readied by IBM, BEA, others

TAGS: SOA

Focusing on SOA, several major software vendors on Wednesday are announcing a specification called Service Component Architecture (SCA), intended to foster development of composite applications.

SCA will allow developers to focus on writing business logic in the building and packaging of applications, according to a source familiar with the announcement. Participating vendors include BEA Systems, IBM, Oracle, SAP, Iona, Siebel and Sybase, the source said. The specification is expected to be submitted to an industry standards body, possibly OASIS, for consideration as an industry standard.

SCA is designed for SOA, unlike platforms such as J2EE, which have been adapted to SOA. SCA is intended to allow development of application assemblies without regard to middleware or language. It features the notion of a service, which is to be defined by an interface that includes a set of operations.

With SCA, a developer, for example, could build a quote to cash application that unites a CRM system with an order management system. Service Data Object technology, for simplifying how applications handle data, is key to SCA.

SCA uses the notion of declarative policies for elements such as security, transactions and reliable messaging. Built for composite applications, it is able to describe assemblies of components that have been written in a variety of programming models and protocols.
