数据库大作业：火车售票管理系统（Python、pyqt5、QT、mysql）

本系统是由五位华工学子（刘同学、陈同学、罗同学、鲁同学、卢同学）在课余时间中对数据库课程设计进行的一次尝试。起因在于，虽然我们都有部分项目经验，然而一般情况下，都是由导师为我们所引导安排去实施任务的，因此在此课程出来后，我们就商量着体验一次，从零开始的自主实现项目过程。这次课设为对我们自身的提升有很大的帮助，为此希望通过这篇文章分享出来。当然，由于是第一次做如此大的工程，也遇到了一些困难的地方，当工作周期长时，也会出现部分拖沓懈怠，在小组之间的鼓励与监督下，完成让课设继续进行。可惜的是对于本系统由于时间较短，其实是开发并不完整的，而且存在并发性等问题没解决。本文主要介绍了火车票管理系统，其中包括其选题功能概述，对该系统的方案方法设计，以及过程实现等内容。由于系统的代码量较大，因此将会较为抽象地对思想进行介绍，在必要时会举出一些实例，还会附上成果展示以及安装方法。最后补充一下这次团伙作案的心得体会，也是非常宝贵的财富。
