本次设计采用Mysql数据库，Mysql是一个非常流行的数据库，它具有很多的优点，包括体积小、开源免费等特点，是一种关系型数据库，可以通过SQL语句进行各项操作。Mysql在近年来特别受欢迎，其主要优势有以下几点：
（1）体积小，安装快。正常的Mysql安装包只有100多M，而且安装速度也快，对服务器的要求比较低，特别适合小型管理系统或网站。
（2）开源免费。Mysql是一个免费的数据库，无需付费即可使用，而且内部代码都是开源的，可以共同维护Mysql生态。
（3）跨平台。Mysql是一个跨平台的数据库，可以在很多操作系统上运行，只需要安装java虚拟机即可。
Mysql提供了JDBC驱动给各类程序进行数据库的链接和操作，本次开发采用Mybatics框架，相比较于传统的JDBC，Mybatics对各类操作进行了封装，实现了半自动的数据操纵。Mybatics极大的提高编程效率，通过Mybatics，可以灵活的根据开发需求来执行SQL语句，可以快速的完成开发任务
