随着经济的发展，企业正向着大型化、规模化发展，而对于大中型企业，员工、职称等跟工资管理有关的信息随之急剧增加。在这种情况下单靠人工来处理员工的工资不但显得力不从心，而且极容易出错。如何设计一个小型企业工资的数据库管理系统，由计算机代替人工执行一系列诸如增加新员工，删除旧员工，工资查询，统计等操作。这样就使办公人员可以轻松快捷地完成工资管理的任务。实现工资的集中管理。
功能：可供财务人员对本单位的人员以及工资进行增加、删除、修改、查询，对人事的管理及工资发放中的应发工资合计等项目由系统自动进行计算；同时系统还可对人事及工资管理情况进行多角度查询
每个子功能介绍
基础功能：登录与增查删改

可以选择登录方式：员工或者管理员（账密默认为admin，123456）

查询分为员工查询和管理员查询，员工只可以根据自己的信息查询，不具备修改的能力，管理员有多种查询功能，在各个模块之间进行操作时，下面有实时的信息显示
管理员具有添加员工，部门等，以及可以添加管理员的功能，修改员工信息，部门信息，设定工资信息。
进阶功能与特色功能：遍历信息与统计
