基于扩展EL的大地测量报表系统

Geodetic Report System Based on Extended EL

通过分析现有大地测量数据报表格式中存在的问题,以基于XML的大地测量数据接口文档为数据模型,建立了以Word文档为模板的EL引擎,使用户能够方便地对大地测量报表模板的样式和内容进行动态控制和修改,实现了数据库管理系统与报表系统、报表格式和数据内容的解耦,增加了报表的灵活性和扩展性。

By Analyzing the problems existing in report format of geodetic data, according to the geodetic data interface based on XML, the extended EL （Expression Language） engine with the user friendly Microsoft Word as its template is developed in this paper. By configuring a template, users can change the data content and design the interface of their reports independently and dynamically, thus flexibility and expansibility of the geodetic report system increased.
