Applying Pattern Oriented Software Engineering to Web Service Development

Abstract

Service-based software development is becoming a prominent paradigm. However, less attention has been paid to the development method of Web service. In this paper, a pattern oriented service development approach (POSE) is presented. Patterns are used as the means to express the results of different development phases, so that the services can be organized and retrieved easily. The business model is constructed explicitly, thus the gap between business goal and services is bridged by the component relationships and the compositions of them. The service maintainer profits from the trace ability because the impact of requirement or design modifications can be better assessed. The patterns support to integrate services of varying levels of granularity.
