SOA oriented web services operational mechanism

Abstract

SOA is a very important guiding theory in constructing information systems recently, the design granularity of information systems will gradually evolve from module to component. At first, this paper shows a SOA oriented information system architecture based on web services. Then it points out that getting web services reasonably and legally is the primary problem in the process of this architecture's realization. According to the different managers of web services, this paper proposes three possible operational mechanisms of web services: (1) Web Service predominant characteristic mechanism guided by large enterprises, (2) Web Services portal mechanism guided by industrial category, (3) Web Service Uniform Alliance (WSUA) mechanism. These three mechanisms may exist and compete with each other at the same time. And the authors think that the ideal operational mechanism is to build a Web Service Uniform Alliance from the perspective of utilizing and saving global intellectual resources. © 2008 by Springer Science+Business Media New York.
