2、阅时间借书量年龄性别图 1-2 实体读者 ER 图用户密码类型 编号图 1- 3 用户实体 ER 图1.2 项目规划图书管理系统是一个典型的数据库应用程序，由应用程序和后台数据库两部分构成。（1）应用程序应用程序主要包括登录，注册，用户信息，读者信息，图书信息管理，借阅图书，综合查询，出版社信息等几个部分组成。（2）数据库 数据库负责对图书信息，用户信息等数据的管理。2 数据库设计说明书21 数据库表结构2.1.1 图书表 book2.1.2 借阅信息表 borrow2.1.2 用户信息表 Reader2.1.4 用户信息权限表 right2.1.5 用户账号表 user2.1.6 管理员账号
