Model Driven Architecture in a Web services world
Level: Intermediate
Keith MantellIT Architect, IBM09 Sep 2003
The Business Process Execution Language for Web Services (BPEL4WS or BPEL for short) is an XML-based standard for defining how you can combine Web services to implement business processes. It builds upon the Web Services Definition Language (WSDL) and XML Schema Definition (XSD). This article describes a new tool from part of the Emerging Technologies Toolkit version 1.1 (ETTK) released on alphaWorks (see Resources for a link), which takes processes defined in the Unified Modeling Language (UML) and generates the corresponding BPEL and WSDL files to implement that process. This capability is used to highlight some of the benefits of the Object Management Groups (OMGs) Model Driven Architecture (MDA) initiative: raising the level of abstraction at which development occurs, which, in turn, will deliver greater productivity, better quality, and insulation from underlying changes in technology.
