基于J2EE的信息服务模型中可扩展的数据字典设计与实现

DESIGN AND IMPLEMENTATION OF AN EXTENSIBLE DATA DICTIONARY IN INFORMATION SERVICE MODEL BASED ON J2EE

传统的信息模型中数据字典的构建模式存在的最大问题,就是不具备可扩展性,无法接纳新资源信息的加入。提出了一种可扩展的数据字典体系的结构设计方法,并基于J2EE规范、MVC设计模式等思想,对该字典体系进行了开发实现。该字典体系目前已经在教育部"高等学校仪器设备和优质资源共享系统"中得到应用和验证。

The largest limitation in traditional data-dictionary design pattern in Information systems is short of extensibility, and it is unadapted for the acceptance of new information resources. In this paper it brings forward an extensible data dictionary system design pattern based on the idea of J2EE platform and MVC design mode, etc. , then exploits and implements the system. Now this data dictionary system has been applied and validated in ＂China higher-education equipments and excellence resources sharing system＂ of National Ministry of Education.
