基于XML的数据模型在报表模块上的应用

The Application of Data Model to Report Module Based on XML

该文针对商业报表工具和报表模块的不足,提出了一个新的报表模块框架,利用基于XML技术定义的数据模型,在报表功能模块与实际数据源之间建立了一个“中间层”。“中间层”的引入,降低了报表模块与实际数据源的耦合度,提高了报表模块的分析能力和可操作性,也为报表模块与其它应用系统之间实现应用集成和数据集成提供了便利。

In order to solve the shortage of commercial report tools and report module,this thesis puts forward a new framework of report module,that is,to establish a middle layer between the report function modules and the data base with the data models based on XML.With the middle layer,it no only can reduce the coupling between report module and the material data source,but also can improve the analysis ability and maneuverability of report module,and it ap-plies the convenience to application integration and data integration between report tools and other application systems at the same time.
