Abstract

This paper provides the context for a deeper understanding of services and SOAs for enterprise-scale software solutions. In particular, it explores services in relationship to the more established concept of software components and it describes how current component-based development practices provide a tried and tested foundation for the implementation of a SOA. Interface-based design is highlighted as the key to both service and component design and it is argued that the interfaces exposed by both have certain distinguishing constraints and criteria. The Unified Modeling Language (UML) is used as a tool to describe logical and implementation designs as well as specific patterns for component and service design.
