基于XML的报表自动生成系统.doc

摘 要 MIS（管理信息系统）开发是当前软件系统开发的热点，许多MIS系统开发都涉及到报表。报表部分的代码相对其它代码而言重复性高、无技术含量且工作量大。现有的报表自动生成系统，如水晶报表等，大部分是生成供用户查看的报表，而忽视了报表也可以作为输入方式的功能。因此，本文提出了一种自动生成包括报表显示和输入功能代码的方法。 首先，本文对报表程序自动生成问题建立数学模型，并对该模型进行分析，找出了问题求解的三个关键点：报表对象的描述、识别和处理。 其次，对报表对象进行了分析并用数学符号进行了描述，对纸质报表和电子报表的识别和处理方法进行了说明。 再次，选定XML作为程序设计语言和报表的形式化描述工具，XML相关技术以其开放性、简单性、可扩展性以及自描述性获得了广泛的应用。本系统采用其中的XML Schema来描述XML文档的合法结构、内容和限制。 最后结合报表程序生成的实际应用，按照软件开发的流程进行了报表自动生成系统的用例分析和系统类的设计，在Delphi 6.0的集成开发环境下实现，并通过了实际报表程序代码生成的测试。 关键词：XML，报表，程序自动生成，XML Schema  Abstract Nowadays, MIS (Management Information System) development is a hotspot of the software system development. Lot’s of MIS system development relate to report. Compare to other code, these codes, related report repeats more, does not have technique and more workload. The report program automation systems existing as Crystal Report are more about the report for user look over. They all ignored the report could also used as a method of input. Therefore, a method of code automation includes report display and input function has been bringing forward in this paper. First of all, this paper sets up a math model and analyses the model. Three key points have been found. They are the description, recognition and handling. Second, this paper analyses the report object and describes it in a form of math. The recognition and handling of the paper report and the electronically report has been explained. Third, the XML (Extensible Markup Language) was selected as the formalization description tool. XML has the property of opened, simple, extensible and self description. This paper adopts XML Schema to describe XML document’s legality structure, content and restrict. At last, the fact application was combined to the report program automation. Use case and class design was processed according to the software development. The system was implemented under Delphi 6.0 integrated development environment. The System overpass the code program generation testing of the fact report. Keywords:XML
