基础数据服务组件的设计与实现

Design and implement of fundamental data service component

在基于组件的开发模式下,企业信息系统应该具有高可重用性的特点。但目前,由于不同企业的基础数据,即各种资源、资源的属性和资源之间的关系往往不同,导致了在不同的企业信息系统中,需要重复去设计、开发相关模块。根据基于组件开发的思想,设计了基础数据服务组件,该组件支持自定义基础数据,并提供接口允许组件使用者调用。通过该组件,避免了在不同企业信息系统中重复开发基础数据模块,提高了复用性。

Nowadays, enterprise information system should be highly reusable through component-based development. However, in different EISes, the fundamental data which contains resources, attributes of the resources and the relationship between these resources, are usually different. The above fact makes the related modules of these systems are reused as expected. Basked on the component-based development view, a ＂Fundamental Data Service Component＂ which allows user to customize the fundamental data ofthe EIS is proposed and designed and interface is provided to use the service. The component is highly reusable for avoiding duplicate development of fundamental data module in EISes.
