Service information management framework based on SOA

Service information management (SIM) of value-added services (VASs) presents two shortages: no enough reusing and burry framework, which lead to cost waste. In order to solve these questions, service-oriented architecture (SOA) is introduced into design of the SIM framework. This paper discusses the SIM framework providing uniform SIM. By classifying service information into three types - user, function and system information - and abstracting respective common attributes, data model of the framework is constructed for SIM unification in data layer. By studying SIM logic, service model includes all component services unrelated with specific VAS. Services in the service model are divided into common part insensitive with specific information and particular part in contrast for the sake of unifying services in different manner. The two categories services are further divided into classes to encapsulate according to service logic. Data and service model makes the framework uniform for reuse and clear to response with change request. Applications on multiple VASs verify feasibility of the framework.
