C程序设计课程设计公交路线查询

1、太湖学院c#程序设计课程设计题目：公交路线查询机 电学院计算机科学与技术专业学 号：学生姓名：班 级：计科84成 绩：2012年 1月 需求分析：随着现代社会的发展，交通也越来越发达，人们也开始不断的外出旅游，不管是市内还是市外对一个准确明了的交通路线需求越来越大，以前我们只能通过电话咨询、看地图、向路人打听来了解讯息，这不仅浪费精力财力时间，而且极为不方便。在这样一个需求下，我们所设计的公交路线查询系统就产生了很大的价值，它能很方便的查询到公交路线，准确的告诉你从a到b该怎么去才最为快捷！这也是我们设计这个系统的初衷！1.功能需求首先我们系统最基本要满足顾客的需求就是公交路线的查询。但是我们

2、清楚的知道，死的列表将造成许多不便，因为路线会随着城市建设而变化，所以我们的路线是可以实时的去更新的，这样就牵扯到再数据库中的更新、删除功能，附带通过报表清楚的显示出来修改后的内容。触发器功能实现公交路线中的一些数值计算，比如几站路等。我们所要实现的就是站点查询、换车查询、线路查询。2.数据需求数据库中包含管理者的账户密码。公交路线数据（包括起始站到终点站的其间所有站点）。3.性能需求客户需要的是一个快捷准确的查询系统，包括一次转车到达以及二次转车到达，不能有任何差错。所以关于线路查询的c#程序语句要考虑周全不能有任何差池。数据库中数据也需要其准确性。概要设计：设计思想： 随着公路规模的不断扩

3、大，公交数量的急剧增加，有关公交管理的各种信息量也在不断成倍增长。面对庞大的信息量，就需要有公交信息管理系统来提公交房管理工作的效率。通过这样的系统，我们可以做到信息的规范管理和快速查询，从而减少了管理方面的工作量。目前，我国各省市的公交查询工作还未实现数字化。整个过程既浪费能源又浪费资源。最后导致浪费时间，无法按时到达目的地。因此，开发一个能够对最新的公交线路进行查询的信息平台就显得尤其重要。所开发的系统将在一定程度上能够克服以上的种种缺点，实现各项工作在线完成，为乘客提供一个完全公开、开放、完善的管理平台，放便了乘客的出行，大大节省了乘客的宝贵时间。通过这样的系统，我们可以做到信息的规范管
