| The primary mission of current enterprise application integration technology(Enterprise Application Integretion, EAI) is about how to integrate effectively the application which is highly heterogeneous and distributed. Had the coarse grain, the tightly coupled and standardized characteristics T he SOA of(Service-Oriented Architecture, SOA) as well as t he Java service integration(Java Business Integration, JBI) technology has provided very good solution. It has the characteristics lik e coarsness and loose coupling.JBI defined one type of pluggable and serving Enterprise Service Bus, ESB construction and abstract service model based on WSDL. It can produce software in the way of service combination. However, the current service arrangement tool which is based on SOA and follows the JBI standard lacks the support of database metadata management and locali zation. This paper studies and realizes service arrangement process metadata management plug-in unit. It tries to in this aspect provide the essential support.The database metadata management plug-in unit that this article studies bases on the framework of Eclipse plug-in unit platform, and supports the arrangement tools of various services. It comprised of the XML storage module and database resource management module and metadata synchronization module. T he main task of this paper includes the following:(1) Profoundly analyzed the SOA service and service arrangement. Analyzed the issue that the SOA service arrangement encounters specifically. Proposed using the localized metadata in the arrangement process.(2) According to the achievement of theoretical research and the technology framework of SOA service arrangement, the eclipse plug-in unit platform was used, and the design has realized the database metadata information management plug-in unit in SOA service arrangement. T he analysis and demonstration to the specific SOA service arrangement process was carried on using local database information. |
