图书馆管理系统java怎么做
先考虑软件环境问题,确定好开发工具和数据库。图书馆管理系统,我的理解就是一个档案管理而已,数据库用sql
server;然后最好设计一个数据库模型和功能模型,把你的系统的主要功能和需要的数据库表有一个雏形。你需要用户登录,则至少有一个用户管理的功能,如果更复杂一点,应该有一个权限管理,日志管理。如果还要分角色,则需要角色管理。然后肯定得有一个图书入库,图书借出,图书归还等等功能;然后就是详细设计了,每个功能模块大概需要哪些更详细的功能点;做好前面几部非常关键,不然后面才发现设计跟需求出现大的偏差,后果就非常严重了;后面就是代码编写测试,纯技术问题,一般问题不大。

JAVA 图书管理系统的设计
挺多的功能,花费的时间不少,所以,一般没人会完全回答的
建议根据这样的 修改一下。。。。
