超市管理系统-1（JavaSwing和Oracle数据库）
2024-04-29 04:24:28
这是我第一次接触Oracle数据库并且利用JavaSwing图形界面编写的一个简单的超市管理系统，其实整体代码后续看了一下，因为JDBC刚接触以及之前JavaSE没学清楚，弄得代码逻辑很繁杂，后面想改又懒，就先记着，有空的话再说==。
具体要求如下：
某超市需要开发购物管理系统进行收银管理，需要为：
（1）系统用户分为管理员和收银员，管理员有用户管理，会员管理和商品管理的功能，收银员通过系统进行收银；
（2）只有会员能在超市购买商品；
（3）系统有一些统计分析功能，如每个月销售最好的商品，不同年龄层（如10年分类一个年龄层）的购物类别，单月收银最高的收银员等。
要求：
（1）后台数据库使用的是Oracle；
（2）超市购物管理系统的所有操作均在可视化界面下进行，前台开发工具不限；
（3）最后提交材料包括代码和文档。
具体代码如下：
