Service-Oriented Computing and the Model-Driven Architecture

Abstract

Service-Oriented Computing (SOC) and the Model-Driven Architecture (MDA) are complementary systems development approaches with the mutual aim of reducing the cost of future systems integration. This chapter introduces the MDA concept and technologies to an SOC audience and employs these technologies to enhance support for SOC through the definition of a domain-specific modeling language for electronic services. The language is defined as an extension of the Unified Modeling Language (UML). Its semantics are defined using a domain model of electronic service systems based on concepts drawn from literature and experience with a range of commercial platforms for the deployment of electronic services.
