1、 基于基于 GISGIS 的市政设施管理系统的市政设施管理系统 摘 要 基于 GIS 的施政设施管理系统采用了以 C#为前台,SQL Server 2000 为后 台的设计方法, 具体实现了电子地图的控制功能, 市政设施数据管理功能和系 统维护功能。 本文详细论述了系统的设计和实现的过程,包括系统的需求分析,概念设 计,逻辑设计,应用程序设计和主程序的调试和试运行情况,最后介绍了本系 统的使用说明。 在需求分析中着重介绍了系统的功能设置及系统的数据流程图 和数据字典。 实体及其之间关系模型的设计即概念设计和逻辑设计也在本文中 进行了详细的说明。 在系统的应用程序设计中, 叙述了系统的主窗口界面
2、和各 部分的功能模块的设计思想及实现的方法。 系统程序调试章节中叙述了在调试 中遇到的问题和解决的方法。 关键词 GIS; 市政设施; 管理系统 Management System Of Municipal Facilities Based On GIS Abstract This dissertation introduces the course of design of Management system of municipal facilities based on GIS, included of requirement analyse, conception design, lo
3、gic design, application design, main program debugging and running test of main program, in the end, it introduces the using explain of the system. In the paragraph of requirement analyse, it particularly introduces general situation of system, function setting, collectivity target, structure of mai
4、n system and subsystem, data flow chart and data dictionary of system. Conception design and logic design which aim at data design for this system, explain the designs of all kinds of information tables. In the part of application design, at first it introduces a software and modules for developing this system, then the main window and function of every part in the window, in the end it explains design idea and method of functions in every subsystem, there are also some code for that. The para
