汽车租赁系统的设计与分析

摘 要

租赁汽车走进社区，走进生活，成为当今生活中不可缺少的一部分。随着汽车租赁业的发展，加强管理和规范管理司促进汽车租赁业健康发展的重要推动力。汽车租赁业为道路运输车辆一种新的融资服务形式、广大人民群众一种新的出行消费方式和汽车生产厂家一种新的汽车营销渠道，在我国迎来良好的发展机遇，但同时也确实有许多问题的需要研究和探讨。

系统主要完成对车辆租赁的管理，包括添加、删除、修改，查询以及用户管理等五个方面。系统可以完成对各类信息的浏览、查询、添加、修改、删除等功能。系统的核心是添加、修改和删除三者之间的联系，每一个表的修改都将联动的影响其它的表，当完成添加或删除操作时系统会自动地完成车辆租赁信息的修改。查询功能也是系统的核心之一。此外，系统有完整的用户添加、删除和密码修改功能。

论文包括需求分析、系统设计、程序设计、系统测试及存在的问题等方面，较为系统地介绍了“在线车辆租赁系统”课题开发的整个过程。

Car Rental System Desige and Implementation

Abstract

Leasing the car walks into the community, walking into the life, becoming the now the life the inside indispensable a part. Lease the development of the industry along with the car, enhance the management is an important motivation to promote car lease the industry health to develop with the norm management. The car leases to be used as road conveyance vehicle a kind of new margin service form, large people crowd a kind of new consume the way out the line to produce factory house a kind of new car marketing outlet with the car, in the our country face to come to good development opportunity, but have also and really many problems need to be studied with inquiry into.

This system mainly completes the management to car’s information include five aspects such as adding, modifying, deleting, searching and the customer management. The system can complete to browse, search, add, delete, modify etc. to each kind of the function of information. The core of the system is the contact of increase, modification and delete, the modifications of each form will affect to other forms, the system will complete the modification of car and of itself while being to complete to increase or delete the operation. Inquiring about the function of searching also is the one of the systematic nucleus. The system contains the integrity function of users increase, delete and the cipher modification, and the report form to print.

This thesis includes requirement analysis, systems design, programming and the system tests and exists the aspects such as question etc, and comparatively systematically introduced the whole course of \
