foreword
The content of this blog is the content of the course. Here I only provide ideas and codes for your reference. Please do not plagiarize easily. It is best to understand the code and realize the requirements of the topic by yourself, so as to exercise your programming and logic skills. In addition, for this course design, I use the command line to operate the mysql database and use IDEA to write java programs.
1. Purpose of course design
The course design of the database system is set up to cooperate with the study of the principles and application development of the database system.
A teaching environment with intensive practice in science and technology, big data, information security, Internet of Things engineering, software engineering, intelligent manufacturing, etc.
It is an important link to transform the theoretical knowledge of relational database into the ability to solve practical problems. Database System Course Design Objectives
The purpose of this course is to deepen the understanding of the theoretical knowledge of relational databases, and master a kind of actual data by using a specific DBMS.
Database management system and master its operation technology, proficiency in the use of database front-end development tools (such as VB, C++, Java,
JSP, Delphi, PowerBuilder, etc.), to further improve students' ability to use database technology to solve practical problems.
2. Overall design
The enterprise personnel management system is mainly used for the entry of employee personal data, record and management of job changes. Using the personnel management system, it is convenient for the company leaders to grasp the movement of personnel and adjust the allocation of talents in time.
1 System requirements analysis
1.1 System function analysis
The personnel management system mainly has the following functional requirements:
Input of new employee information.
Automatically assign employee numbers and set initial user passwords.
Detailed records of personnel changes, including job and department adjustments.
Query and modify employee information, including employee personal information and passwords.
1.2 System function module design (division)
According to the functional requirements of the system, the system can be decomposed into several modules to
Design the application program interface separately, as shown in Figure 1.
1.3 Relationship with other systems
This system is the basic part of the company's management information system. Provide basic information of employees for other subsystems, such as attendance management system, salary management system and employee training system. At the same time, it provides password authentication and authority distribution functions for employee logins for other systems.
1.4 Data flow chart
The data flow of the personnel information management system is shown in Figure 2, and all data is input by personnel department managers.
2 Database design
2.1 Analysis of database requirements
According to the data flow diagram, the following data items and data structures can be listed:
员工信息：员工号、密码、权限、姓名、性别、生日、专业、通讯地址、 电话、email、当前状态、其他。
人事变动：记录号、员工、变动、详细描述。
所需的外部数据支持：
部门设置：部门编号、名称......
2.2 数据库概念结构设计
图3 是本系统所需数据的 E-R 模型图。
2.3 数据库逻辑结构设计
根据系统E—R 图，本系统需要有 2 个数据表分别来存放员工个人信息和人事变动记录。并且需要 1 个外部数据表(部门信息)的支持。同时部分记录字段需要用代码来表示，因此需要 3 个代码表来分别记录教育程度、职务和人事变更的代码。这 6 个数据表的结构如表 1 到表 6 所示。
2.4 数据库的建立
2.4.1 数据库的建立
创建需要一个数据库即可
2.4.2 初始数据的输入
本系统中需要输入的初始数据包括：部门信息、受教育程度代码、职务代码和人事变动代码。受教育程度代码和人事变动代码如表7 到表 8 所示，部门信息代码和职务代码的设置如图4 所示。
图4、部门信息代码和职务代码
3 各功能模块的设计与实现
3.1 功能说明
1、增加新员工
2、人事变动
3、员工信息查询修改
4、加密模块
5、员工登录
3.2 用户界面设计
完成数据库创建和功能说明以后，我们可以进行下一步工作，即设计用户界面。我们把人事信息管理系统的窗体分以下成 6 个主要部分。
1、主窗口的创建
2、增加新员工窗体的创建
3、人事变动窗体的创建
4、员工信息查询修改窗体的创建
5、加密模块的创建
6、登录窗口的创建
3.3 各功能模块的实现
1、增加新员工的实现
2、人事变动的实现
3、员工信息查询修改的实现
4、加密模块的实现
5、员工登录的实现
4 系统实现
