SCA Based Integration - Bindings EIS Import SCA Module B Web Service App SCA Import WS Import JMS Application WBI Adapter WebSphere Adapter Web Service App SCA Module A JMS App WBI Adapter WebSphere Adapter J2EE Application SCA Module A J2EE Application We have native ‘SCA’ bindings for SCA to SCA (modules). In addition to that, we allow SCA components to be called from (look left) a variety of client programming styles and we allow SCA programs to view a number of services as WSDL describe SOA services (look right) JCA JCA JMS Export JMS Import SCA Export WS Export EIS Export SCA Export WS Export SCA Import WS Import SLSB Import

13. SCA and SDO Standardization What we announced in November, 2005 A series of specifications aimed at developers building solutions and components using Service Oriented Architecture principles: – Service Component Architecture (SCA) – Service Data Objects (SDO) Meeting Customer Needs: – Simplification of Development (Simplify the enterprise developers life) – Composition and Implementation of Services – Multiple Language support (Java, C++, BPEL, PHP) – Flexible Quality of Service – Broad Industry Support – A procedure for obtaining community feedback Early Code Availability – Runtime offering for Developers, supporting the programming model in C++ and Java The specs on the IBM web site: http://www.ibm.com/developerworks/library/specification/ws-sca/
