毕业设计（论文）-PB房屋管理系统设计.doc

. 摘 要 本文以房屋管理系统开发过程为背景，全文分为目录、需求分析、系统分析、以及系统的实现等全过程。本系统以Windows XP为平台，选用了易学易用的可视化的PowerBuilder 6.5为开发工具，结合单位实际并经过查资料，利用软件工程化思想，总体上用结构化生命周期法进行系统分析和设计，采用快速原形法来实现。在程序设计与调试上采用了自上而下。逐步细化，逐步完善的原则。采用结构化的功能模块设计系统功能，可读性好，易于扩充。基本功能全面。本系统用户界面友好、清晰、操作简便，易学易用，系统可读性好，易于维护、更新。安全性好。进入系统前验证先验证用户身份，防止他人非法进入。利用传统下拉菜单功能进行选择，方便、快捷、一目了然。自动计算各种数据并进行报表打印。查询较方便，可进行各类查询，系统可靠性好。 关键词：信息管理系统，系统设计，数据库，PowerBuilder Abstract This text with the house manages the system development process for background; the full text is divided into the realization of the catalogue, the need analysis, the system analysis, and system etc. whole process. This system take the Windows XP as the terrace, choosing to use easy to learn and easy the PowerBuilder that can see to turn that use in order to develop the tool, combine the unit to combine physically has been checked the data, make use of the software engineering to turn the thought, total up turns the life cycle method to carry on the system analysis and design with the structure, adopt fast original shape method to carry out. At program design with adjust to try up adapting from top to bottom. Gradually thin turn, gradually perfect principle. Adopt a design of the function mold system function that structure turn, readability good, be easy to the enlargement. The basic function is overall. This system customer interface amity, clear, operate simple, easy to learn use easily, the system readability good, be easy to the maintenance and renew. Safety good. Before entering the system verified to verify the customer body first, prevent?from the others unlawful entry. Make use of under tradition pull the menu function to carry on the choice, convenience, fast, is clear at a glance. Compute various data and carry on statements print automatically. The search is more convenient, can carry on each kind of search, the system credibility good.
