摘要
针对传统信息模型中,数据字典的构建模式无法接纳新资源信息的加入,扩展性较差的不足,提出了一种可扩展的数据字典体系的结构设计方法。用UML对系统进行分析和建模,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。
One of the limitation for traditional data-dictionary design pattern in information systems is short of expansibility, and it is unadapted for the appearance of new information resources. In view of the weakness of traditional design pattern, an expansile data dic- tionary design pattern is brought forward. It is analyzed and modeled by UML and implemented based on the J2EE platform and MVC mode. Now this data dictionary system is applied and validated in ＂China high-education equipments and high quality resources sharing system＂ of national ministry of education.
