S家具企业始建于1954年,是一家有着40多年历史的老厂。在建厂初期,以生产家庭生活木制品为主(桌、椅等)。到了80年代后期,该厂在生产家庭生活木制品的基础上,扩大生产,开始生产办公桌椅及具有一定行业特色的家具产品(如宾馆专用等)。进入新世纪以来,S家具企业实行了股份制,且不断创新,增加产品的种类,来满足现代人们的生活需求。S家具企业还通过了国际质量认证,对企业的质量管理业务流程进行了确认,并建立了有效的控制手段。S家具企业现有在职员工五百余人,其中管理和技术人员一百余人。从学历层次看,S家具企业大专以上文化程度占员工总数的30%以上。在调查过程中发现,S家具公司在管理方面存在一定的不足—即是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。

二、员工工资系统设计

2.1系统功能分析

工资管理系统系是为了更好地实现工资各种信息的管理以及各种信息的安全性管理。本系统主要对查看员工的各种工资信息需求所设计的,可以很好的管理数据。 本系统的主要功能由以下几个部分组成:

经过调研及分析,工资管理信息系统主要完成以下功能: (1) 员工信息数据的输入; (2) 员工信息的添加、修改、删除; (3) 企业工资的基本设定; (4) 员工个人工资的汇总; (5) 员工个人工资的查询。

三、数据库设计

3.1数据流需求分析

登陆信息 返回信息 登 录 操 作 户 用 数据库 错误信息 寻找信息 数据库需求分析——数据流图

3.2概念模型设计

根据系统数据流图和数据字典,得出系统的概念模型(E-R)如图所示。

3.3逻辑结构设计

根据上述概念模型设计得出的E—R图,我们可以得出系统中涉及的主要实体有2个,其结构如下: 员工信息表:
