公交路线查询系统的设计与实现摘 要 随着科学技术的不断提高，计算机科学日渐成熟，其强大的功能已为人们深刻认识。它已经深入到日常工作和生活的方方面面，比如文字处理、信息管理、辅助设计、图形图像处理、教育培训以及游戏娱乐等。 公交路线查询系统是用计算机管理公交路线信息的一种计算机应用技术的创新，在计算机还未普及之前公交路线查询都是由人们人工查询的方式来操作的。现在一般的公交路线查询都采用计算机智能化管理，采用计算机作为工具的实用的公交路线查询系统来帮助人们进行更有效的公交路线查询。公交路线查询系统是典型的信息管理系统，其开发主要包括后台数据库的建立和维护以及前端应用程序的开发两个方面。对于前者要求建立起数据一致性和完整性强、数据安全性好的库。而对于后者则要求应用程序功能完备，易使用等特点。 经过分析，使用 Microsoft公司的 Visual Basic开发工具，利用其提供的各种面向对象的开发工具，尤其是数据窗口这一能方便而简洁操纵数据库的智能化对象，首先在短时间内建立系统应用原型，然后，对初始原型系统进行需求迭代，不断修正和改进，直到形成用户满意的可行系统。数据库同样应用Microsoft公司的Access。 因为本人能力有限，加上时间紧迫，所以设计出来的系统可能功能比较简单，另外系统是单机版，不能实现网络互联操作，这些都有待于我在以后的工作学习中进一步改进。 【关键字】公交车查询管理；Visual Basic；Access Abstract As the development of the science and technology, computer science increasingly mature, and its powerful functions gives people deeply impression that it has it has to go down to the daily work and life, such as word processing, information management, aided design, graphics and video processing, as well as education and training game entertainment. The information search system design for bus route using computer management information is a innovation in the computer technology, bus enquiries are managed by the working people to operate manual enquiries before the public of computer. The general public enquiries have adopted computer intelligent vehicle manage now, people can effectively search the bus route by the automatic management procedures. The information search system design for bus route is a typical information management system, including its main development background to the establishment and maintenance of the database and front-end application development. After analysis, I use Microsoft visual basic development tool companies, the use of its various object-oriented development tools especially data, that can be easily accessible and concise window manipulation database intelligent objects, the first prototype application system in a short time and then, computation of the initial prototype system needs to constantly revi
