简单的火车票查询系统

摘 要

针对火车票查询的实际情况，按照软件工程的结构化设计思想，经过项目的可行性研究和需求分析、总体设计、详细设计，以及编码实现和调试等步骤设计开发了简单的火车票网上查询系统。并运用数据流图和数据字典、E-R图和数据库逻辑结构、层次图、系统流程图、以及程序流程图，对该系统的数据需求、数据库、系统软件结构、系统流程、以及处理过程等进行了分析和设计。

本次课程设计利用JSP 开发工具和SQL Server 2000数据库来开发这个火车票网上查询系统。该系统要解决的是火车票查询工作所要解决的问题，可以满足火车票查询的基本要求，包括查询票信息等方面的功能。该系统能运用到旅游网站对火车票查询的工作中，根据用户的需求，快捷方便的为用户提供服务。 关键词：计算机技术；火车票查询系统；JSP

A simple train ticket query system

Abstract

In view of the actual situation of train ticket inquiries, in accordance with a structured software engineering design, the project feasibility study and in the demand analysis, overall design, detailed design, coding and debugging steps as well as the design and development of simple train ticket query system. And use the data flow diagram and data dictionary, E-R diagram and database logical structure, hierarchy diagram, system flow chart, and program flow chart of the system, data requirements, database, system software structure, system process, and the process is analyzed and design.

The curriculum design using JSP development tools and SQL Server 2000 database to develop the train ticket query system. The system is to solve the train ticket query work to solve the problem, can meet the basic requirements of train ticket inquiries, including query ticket information and other functions. The system can be applied to tourism website to train ticket query work, according to user needs, fast and convenient for the user to provide services.

Keywords: computer technology; train ticket query system of JSP.
