《高级程序设计语言》图书管理系统设计报告 学院:国土资源工程学院专业:测绘工程成员:********************************指导教师:黄云铠日期:2014年11月5日
1系统设计设计目标本系统是针对图书管理工作过程进行设计的,主要实现如下目标:注册用户可以登录此系统;非注册用户注册后可以使用本系统;读者可以查询、借阅、归还图书等;管理员可以对读者、图书进行管理。1.2数据库设计概述1.2.1概念结构设计将从需求分析中得到的数据信息抽象为概念模型,经分析可得到数据库的E-R模型。如图所示。图书名称作者编号出版日期价格种类出版社图1-1图书实体ER图密码密码读者姓名编号专业借阅时间借书量年龄性别图1-2实体读者ER图用户用户密码类型编号图1-3用户实体ER图1.2项目规划图书管理系统是一个典型的数据库应用程序,由应用程序和后台数据库两部分构成。(1)应用程序应用程序主要包括登录,注册,用户信息,读者信息,图书信息管理,借阅图书,综合查询,出版社信息等几个部分组成。(2)数据库数据库负责对图书信息,用户信息等数据的管理。2数据库设计说明书2.1数据库表结构2.1.1图书表book2.1.2借阅信息表borrow2.1.2用户信息表Reader2.1.4用户信息权限表right2.1.5用户账号表user2.1.6管理员账号表usererheper2.2数据关系图2.3图书管理系统暂有数据(模拟运行)2.3.1管理员学工号:2014701020姓名:邢吉昌密码:1112.3.2普通用户学工号:2014701021姓名:猪八戒密码:333学工号:2014701022姓名:孙悟空密码:4442.3.3图书信息编号作者书名出版社出版日期价格书类H319584781MARKC#入门经典清华大学出版社2011/4/521.56计算机H319584782哪吒和猴子的那些事天庭文印2010/1/2216.5情感H319584783二郎神我也可以闹天宫天庭文印2009/8/129.32技术3程序功能的实现3.1登陆界面已注册用户登录时,用户类别选择普通用户或管理员,不选择会出现提示主要代码如下:usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;usingSystem.Data.SqlClient;namespaceWindowsFormsApplication1{publicpartialclassLoginForm:Form{publicstringpassword;privateintErrorTimes;stringUser,Pwd;boolflagshow=false;privateboolyanzhengshuru(){password=textBox3.Text;if(Typename.Text.Trim()==""){MessageBox.Show("请选择登录类型","登录提示",MessageBoxButtons.OK,MessageBoxIcon.Information);Typename.Focus();returnfalse;}elseif(loginid.Text.Trim()==""){MessageBox.Show("请输入用户名","登录提示",MessageBoxButtons.OK,MessageBoxIcon.Information);loginid.Focus();returnfalse;}elseif(password==""){MessageBox.Show("请输入密码","登录提示",MessageBoxButtons.OK,MessageBoxIcon.Information);textBox3.Focus();returnfalse;}else{returntrue;}}publicLoginForm(){InitializeComponent();}privatevoidcancelbtn_Click(objectsender,EventArgse){Application.Exit();}privatevoidLoginForm_Load(objectsender,EventArgse){}privatevoidLoginForm_Closing(objectsender,FormClosingEventArgse){Application.Exit();}privatevoidloginbtn_Click(objectsender,EventArgse){if(yanzhengshuru()){if(Typename.Text.Trim()=="管理员"){SqlConnectionconConnection=newSqlConnection(@"DataSource=.\sqlexpress;InitialCatalog=学生管理数据库;IntegratedSecurity=True");conConnection.Open();stringcmd="selectAdminID,AdminPassfromuserhelper";SqlCommandcom=newSqlCommand(cmd,conConnection);SqlDataReaderreader=com.ExecuteReader();while(reader.Read()){User=reader["AdminID"].ToString();Pwd=reader["AdminPass"].ToString();if(User.Trim()==loginid.Text&Pwd.Trim()==textBox3.Text){flagshow=true;}}reader.Close();conConnection.Close();if(flagshow==true){this.Hide();adminf1=newadmin();f1.ShowDialog();}}else{if(Typename.Text.Trim()=="普通用户"){SqlConnectionconConnection1=newSqlConnection(@"DataSource=.\sqlexpress;InitialCatalog=学生管理数据库;IntegratedSecurity=True");conConnection1.Open();stringcnd="selectReaderID,ReaderPasswordfromreader";SqlCommandcnm=newSqlCommand(cnd,conConnection1);SqlDataReaderreader1=cnm.ExecuteReader();while(reader1.Read()){User=reader1["ReaderID"].ToString();Pwd=reader1["ReaderPassword"].ToString();if(User.Trim()==loginid.Text&Pwd.Trim()==textBox3.Text){flagshow=true;}}reader1.Close();conConnection1.Close();if(flagshow==true){this.Hide();读者查阅f1=new读者查阅();f1.ShowDialog();}else{MessageBox.Show("用户名不存在或密码错误!","提示");ErrorTimes++;if(ErrorTimes>=3){MessageBox.Show("登录次数过多,程序将关闭");//Application.Exit();return;}}}}}}privatevoidlabel1_Click(objectsender,EventArgse){}privatevoidlabel2_Click(objectsender,EventArgse){}privatevoidlabel3_Click(objectsender,EventArgse){}privatevoidbutton1_Click(objectsender,EventArgse){this.Hide();注册f1=new注册();f1.ShowDialog();}privatevoidusercomboBox_SelectedIndexChanged(objectsender,EventArgse){}privatevoiduseracctxt_TextChanged(objectsender,EventArgse){}privatevoidtextBox3_TextChanged(objectsender,EventArgse){}}}3.2登陆界面如果学号已经存在,则会出现“*用户名已经存在,请重新输入”的提示,当重新输入密码时,如果两次密码不相同,则会出现“*请注意,两次密码不一样”的提示主要代码如下:usingSystem;usingSystem.Collections.Generic;usingSystem.ComponentModel;usingSystem.Data;usingSystem.Drawing;usingSystem.Linq;usingSystem.Text;usingSystem.Windows.Forms;usingSystem.Data.SqlClient;namespaceWindowsFormsApplication1{publicpartialclass注册:Form{public注册(){InitializeComponent();}publicboolUserFlag;privatevoidtextBox3_TextChanged(objectsender,EventArgse){if(textBox2.Text.Trim()!=textBox3.Text.Trim()){label6.Visible=true;}else{label8.Visible=true;label6.Visible=false;}}privatevoid注册_Load(objectsender,EventArgse){}privatevoidtextBox1_TextChanged(objectsender,EventArgse){SqlConnectionconConnection=newSqlConnection(@"DataSource=.\sqlexpress;InitialCatalog=学生管理数据库;IntegratedSecurity=True");conConnection.Open();stringcmd="selectReaderIDfromreader";SqlCommandcom=newSqlCommand(cmd,conConnection);SqlDataReaderreaderUser=com.ExecuteReader();while(readerUser.Read()){if(textBox1.Text==readerUser["ReaderID"].ToString().Trim()){label7.Visible=true;UserFlag=true;return;}elseif(textBox1.Text!=readerUser["ReaderID"].ToString().Trim()){label7.Visible=false;label9.Visible=true;UserFlag=false;}}}privatevoidbutton1_Click(objectsender,EventArgse){intindex=textBox4.Text.IndexOf("@");if(index<1){label10.Visi
