C#与SQLserver数据库技术建立一个通用工资管理系统，该系统为提供了查询、增加记录、删除等功能，功能比拟的齐全，并对工资进行了统计如津贴管理、报表统计等。根本上能满足管理员和公司的要求。此次数据库课程设计的主要设计如下：原理分析、程序设计过程、程序实现和程序调试以及数据库的设计。需求分析、概要结构设计、逻辑结构设计、物理结构设计和数据库的实施和维护。主要包括两大大功能模块：管理员管理界面设计。员工管理界面设计。二、需求分析功能需求分析：该通用工资管理系统具备以下功能：管理员通过输入用户名和密码进下该系统后，可以进行一些根本查询〔员工信息查询、工资奖金信息查询〕、工资管理〔计算总工资、奖金管理〕；通过输入密码，可以进行查询员工的数据〔工资，奖金，税收等〕。具体功能的详细描述如下在首页进行选择，员工与管理员通道点击[管理员登陆]3、用户名和密码即可进入[工资管理]功能窗体，在此可以选择功能，添加，查询，人员列表4、点击[添加]功能窗体，添加员工工资信息。5、点击[查询]功能窗体，输入员工号即可查询员工信息。6、点击[人员列表]功能窗体，可查看所有员工的列表，这界面内可以进行删除操作。7、点击[员工登陆]8、用户名和密码即可进入[员工工资查询]功能窗体，在此可以选择查询根本信息，查询工资信息。9、在[查询根本信息]，员工可自己查看自己的信息。10、在[查询工作信息]，员工可自己查看自己的工作信息。数据流需求分析：登陆信息返回信息用户用户登录操作数据库错误信息寻找信息数据库需求分析——数据流图三、概要设计根据需求分析阶段得到的功能需求，管理员、员工通过输入用户名号和密码进下该系统后，可以进行一些根本查询〔员工工资信息查询、信息查询〕、还可以进行员工删除和添加员工的操作，员工通过登录并输入密码，可以进行查询自己的数据〔工资，根本信息〕。模块功能大概可以分为如图下几个个方面：图如以下图所示四、物理设计1.选择[登陆]那么会进入相应登陆界面。2.选择[员工登陆][管理员登陆]按钮命令3.选择[管理员登陆]按钮命令即可进入[管理]功能窗体。4.选择[员工登陆]按钮命令即可进入[员工查询]功能窗体。5.在[添加]，管理员对员工的信息进行添加。6.在[查询]，可以对员工查询并进行修改。7.在[列表]，可以查看所有员工的列表。五、详细设计〔1〕数据库的E-R图及合并局部视图生成E-R图员工信息E-R图：病假天数工作天数Empinfotale姓名工龄银行卡年龄病假天数工作天数Empinfotale姓名工龄银行卡年龄工种名称用户名性别员工工资信息E-R图：银行卡号退休工资国家税收Salaryinfo工作天数根本工资奖金员号总工资实际工作银行卡号退休工资国家税收Salaryinfo工作天数根本工资奖金员号总工资实际工作管理员用户E-R图：admin用户用户号密码〔2〕数据库结构设计根据上面概念结构设计阶段得到的E-R图，下一步应该将它转化为关系模型。可以得到对应的关系模式为：Empinfotale([cin],[name],[year],[sex],[workyear],[position],[creditcard],[workday],[illday])Salaryinfo([cin],[bonus],[salary],[individual],[individual2],[workout],[workday],[Reality],[creditcar])admin([id],[cin],[password])数据库表的建立：〔sql语句及截图〕语句如下：CREATETABLE[dbo].[Admin]([id][int]IDENTITY(1,1)NOTNULL,[cin][int]NULL,[password][char](20)NULL,〕；CREATETABLE[dbo].[Empinfotale]([cin][int]NOTNULL,[name][char](8)NULL,[year][int]NULL,[sex][char](4)NULL,[workyear][int]NULL,[position][char](18)NULL,[creditcard][char](19)NULL,[workday][int]NULL,[illday][int]NULL,〕；CREATETABLE[dbo].[Admin]([id][int]IDENTITY(1,1)NOTNULL,[cin][int]NULL,[password][char](20)NULL,〕；六、调试分析〔1〕数据库的表的建立与实现admin表的建立：Salaryinfo表的建立：Empinfotale表的建立：数据库的运行和截图:选择登录界面截图：管理员登录后：查询界面：添加界面：显示所有信息：〔2〕调试与运行程序分析及存在的主要问题在此次课程设计中的主要数据库局部为数据库的连接局部，该局部直接影响到数据库与应用程序的接口实现，而且必须注意数据库的名称与连接数据库是取的名称一致。七、小结该工资管理系统总体说来功能不是很齐全齐全，只具备管理员和员工的一些根本的功能；数据库的设计方面，建有员工信息表、个人信息表、工资表。数据库中存在一些问题，如数据冗余，不够完善。但在做课程设计的过程中也遇到很多问题，一开始时其中最大的问题是不知道用哪种编译工具，后来选择了MicrosoftVisualStudio,在编写程序时，编写程序起来也有点困难，但是也越来越顺利了。经过调试后终于把自已想到实现的功能一步步实现了，通过这次课程设计使我收获了好多，熟悉了C#的运用，还复习了数据库相关语句的编写。此次课程设计让我感受颇多：做一个数据库其实是一件很有趣的事情。想到自己可以创立一个小型的数据库系统，有点学习后的满足感。数据库的建立并非难事，难点在于数据库的连接和编程语言的选择。C#的功能很强大，这也是我以后需要学习的课程，于是我毅然选择了它。再就是建立数据库系统的步骤，我的经验就是要先总体规划，再局部整理。先做好总的界面，再通过该界面的布置一步一步实现其功能！同时我体会到：熟练的编程能力，对知识运用的强烈渴望及其创新和团队的合作精神设做好一个大型数据库的根底。因此通过此次课程设计我明显感觉到自身的缺乏，并希望以后能更加用心地运用所学知识和学习新的知识。在这个系统中我主要负责了数据库的建立和管理员管理的页面设计，虽然做的不是很好的，但是让我们学到了很多关于数据库连接方面的知识。我会继续完善下去的。八、附件一、程序代码选择登陆页面usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;usingSystem.Configuration;namespaceGZMS{publicpartialclassindex:Form{publicindex(){InitializeComponent();}privatevoidbutton1_Click(objectsender,EventArgse){Form1indexform=newForm1();indexform.Owner=this;indexform.Show();this.Hide();}privatevoidbutton2_Click(objectsender,EventArgse){Form11indexform=newForm11();indexform.Owner=this;indexform.Show();this.Hide();}}}验证用户名登陆页面usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;usingSystem.Data.SqlClient;usingSystem.Configuration;namespaceGZMS{publicpartialclassForm1:Form{publicForm1(){InitializeComponent();}protectedoverridevoidOnClosed(EventArgse){Application.Exit();}privatevoidindex_Click(objectsender,EventArgse){stringusername=txusername.Text;stringusrepaw=txuserpaw.Text;if(username==""||usrepaw==""){MessageBox.Show("请输入用户名或密码","提示");return;}SqlConnectionsqlCon=newSqlConnection(ConfigurationManager.ConnectionStrings["GZB.Properties.Settings.ConnectionString"].ConnectionString);//stringConnectionString=@"DataSource=(local);InitialCatalog=GZB;User=sa;Password=admin;IntegratedSecurity=True";//SqlConnectionsqlCon=newSqlConnection(ConnectionString);//创立Connection对象//DataSource=.;InitialCatalog=数据库名;IntegratedSecurity=Trueid=用户名password=密码try{sqlCon.Open();stringsql=String.Format("selectcin,passwordfromAdminwherecin='{0}'andpassword='{1}'",username,usrepaw);SqlCommandcomm=newSqlCommand(sql,sqlCon);SqlDataReaderc=comm.ExecuteReader();if(c.Read()){this.DialogResult=DialogResult.OK;//触发确定¨//MessageBox.Show("成功|","登陆成功|",MessageBoxButtons.OK);searchadd=newsearch();add.Owner=this;add.Show();this.Hide();}else{MessageBox.Show("成功","登陆成功|",MessageBoxButtons.OK);}}catch(SqlExceptionex){MessageBox.Show("数据库错误","错误");}finally{sqlCon.Close();}}privatevoidquet_Click(objectsender,EventArgse){Application.Exit();}}}功能选择页面usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;usingSystem.Data.SqlClient;usingSystem.Config
