sqlserver数据库管理系统的简单实现

java与sqlserver数据库大赛项目的简单实现(药品进销系统)

近期参加数据库大赛,过程中利用sqlserver数据库与java(AWT组件)语言写了一个简单的药品进销系统.

在这次项目中 我明确了关于这个管理系统的各项功能 包括登录 注册 查找药品 买药 卖药 以及对卖药后的客户记录 库存数量

以下是关于这个数据库的相关信息

数据库的四张表

在这插入图片描述
这四张表分别对应了售卖药品后所卖客户的信息,买药或售药后药品的存储信息,药品 的相关信息 包括生产日期 ,年限,名称等,员工信息.

JDBC类

之后便是JDBC,JDBC是java连接数据库的工具类 方便利用java语言实现数据库的增删查改，对于数据库操作的相关命令 不要忘了导入sqlserver的jar包,同时在url那一行不要忘记数据库的名字.
