异构服务和分布式数据的动态集成

Dynamic Integration of Disparate Services and Distributed Data

对于企业而言,充分利用内、外部资源来提高效率是极为重要的。给出了以企业服务总线ESB为基础的服务-数据动态集成框架,在此框架中将业务操作分解为多个服务-数据流,同时提出了一种新的服务-数据流评价策略以衡量分解的合理性。利用动态路由机制完成抽象服务与服务提供者、抽象数据与数据源之间的映射。服务-数据路由对抽象服务描述表ASDT、抽象服务映射表ASMT、抽象数据描述表ADDT和抽象数据映射表ADMT进行更新来消除其中的冲突。最后将研究应用于"黑龙江省运政系统"的设计中,证明了该方法的可行性。

It is very important for enterprises to utilize resources efficiently inside and outside in order to improve the efficiency. A new framework that services and data are composed dynamically based on enterprise service bus（ESB） was proposecl, in which business process was analyzed into service-data flows and the weight computation method was used for evaluating the separating rationality. Dynamic routing mechanism was applied to map abstract service to service providers and map abstract data to datasources. Abstract service description table （ASDT）, abstract service mapping table （ASMT）, abstract data description table （ADDT）, and abstract data mapping table （ADMT） were modified by service data router for solving the conflicts. Finally, the method has also been applied in Yunzheng System of Heilongjiang Province,in order to prove it＇s feasibility.
