基于元数据模型的电子政务检索系统的设计与实现

The Design and Implementation of E-government Retrieval System Based on Metadata Model

在当前互联网和计算机飞速发展的形势下,电子政务类系统的数据量也逐渐呈现指数型增长的态势。如何在不影响报表传统格式展现的前提下对这些数据进行单表内检索以及多表间关联检索,已经逐渐成为当下亟须解决的一个问题。本文从传统报表结构出发,以用友插件为报表载体,对报表的元数据进行了模糊判断和精确判断的分类,并在此基础上提出了全新的模板检索机制。实践证明,该方法大大提高了报表全文检索的易用性以及可扩展性。

With the current rapid development of the Internet and computer technology, data quantity of E-government system also gradually shows exponential growth. Under the condition of no affecting the traditional format of report, it has become a problem to implement the retrieval of tables independent and tables associative. This paper is based on traditional structure of the report, and UFIDA plugin is used as report carrier, and the metadata are classified as fuzzy judgment and accurate judgment. Finally this paper puts forward a new template mechanism. The result has proved that this method greatly improves the report full text search usability and scalability.
