图书馆一个数据库设计SQL

综合设计性实验
为图书馆设计一个数据库，此数据库对每个借阅者保存读者记录，包括：借书证号、姓名、性别、单位、可借数量。

对每本书记录：书号、书名、作者、出版社。

对每本被借出的书有：读者号、借出日期、应还日期。

可以随时查阅书库中的书籍信息，所有的书籍均由书号唯一标识；可以随时查阅书籍借还情况，系统约定任何人可以借多本图书，任何一种图书可以为多人所借，借书证号具有唯一性。

要求：
1.基于《数据库概论》中所学的知识分析该数据库的基本结构，
2.用Transact-sql命令完成如下要求：
（1）创建数据库和数据表，定义每个表的主键和外键，为每个属性选择合适的数据类型，定义每个属性是否允许空值，是否有默认值等；
（2）结合具体情况为数据库表设置合理的约束或规则；
（3）如果需要，为数据表设计合理的触发器；
（4）使用SQL语句，在你设计的每个表中插入至少3条数据，要求记录满足数据约束要求，且尽量真实可信；
（5）自行设计查询要求，给出经常需要用到的查询语句。

3.写出完整的实验报告。

图书管理系统数据库设计

图书管理系统数据库设计1. 引言图书管理系统是一个用于管理图书馆馆藏图书的软件系统。

它提供了图书的借阅、归还、查询等功能，方便读者进行图书借阅和图书馆管理员进行图书管理。

本文档将介绍图书管理系统的数据库设计。

通过组织图书、读者、借阅记录等相关数据，实现图书管理系统的各项功能。

2. 数据库设计2.1 数据库结构图书管理系统的数据库主要包含以下几个表：•图书表（books）：存储图书的基本信息，如图书编号、名称、作者、出版社等。

•读者表（readers）：存储读者的基本信息，如读者编号、姓名、性别、年龄等。

•借阅记录表（borrow_records）：存储图书的借阅记录，包括借阅编号、借阅日期、归还日期、读者编号等。

2.2 数据库字段2.2.1 图书表（books）•book_id：图书编号，主键•book_name：图书名称•author：作者•publisher：出版社•publication_date：出版日期•price：价格2.2.2 读者表（readers）•reader_id：读者编号，主键•reader_name：读者姓名•gender：性别•age：年龄•phone：联系电话2.2.3 借阅记录表（borrow_records）•record_id：借阅记录编号，主键•book_id：借阅图书编号，外键•reader_id：借阅读者编号，外键•borrow_date：借阅日期•return_date：归还日期2.3 数据库关系•图书表与读者表之间是多对多的关系，通过借阅记录表进行关联。

•图书表与借阅记录表是一对多的关系，一个图书可以对应多条借阅记录。

•读者表与借阅记录表也是一对多的关系，一个读者可以借阅多本图书。

2.4 数据库约束•图书编号（book_id）在图书表中是唯一的，不能重复。

•读者编号（reader_id）在读者表中是唯一的，不能重复。

•借阅记录编号（record_id）在借阅记录表中是唯一的，不能重复。

高校图书馆管理系统(SQL数据库)

高校图书馆管理系统(SQL数据库)高校图书馆管理系统(SQL数据库)随着信息技术的发展，高校图书馆管理系统在图书馆运营中的重要性日益凸显。

为了更好地管理馆藏资源和提供优质的服务，许多高校选择使用SQL数据库作为图书馆管理系统的基础。

本文将探讨高校图书馆管理系统中SQL数据库的应用及其优势。

一、图书馆管理系统简介图书馆管理系统是高校图书馆中的核心业务系统，它涵盖了图书馆的各个环节，包括图书采购、编目、借阅、归还、查询等功能。

通过图书馆管理系统，读者可以方便地查找、借阅和归还图书，图书馆工作人员也可以高效地管理馆藏资源。

二、SQL数据库在图书馆管理系统中的应用1. 数据库设计在图书馆管理系统中，SQL数据库的设计是至关重要的一环。

通过合理的数据库设计，可以提高系统的查询效率和安全性。

例如，可以将图书馆中的书籍信息、读者信息、借阅记录等存储在不同的数据库表中，并通过外键关联它们，实现数据的联合查询。

2. 图书馆资源管理SQL数据库提供了强大的查询和管理功能，可以方便地进行图书馆资源管理。

通过SQL语句，图书馆管理员可以实现对图书馆馆藏资源进行分类、检索和统计。

同时，SQL数据库还支持数据的备份和恢复，保障了图书馆数据的安全性。

3. 借阅管理借阅管理是图书馆管理系统中的核心功能之一。

SQL数据库可以存储读者的借阅记录，包括借阅时间、归还时间、借阅状态等信息。

通过SQL查询语句，管理员可以实时监控图书的借阅情况，及时催还逾期图书。

4. 读者管理通过SQL数据库，图书馆管理员可以方便地管理读者信息。

包括读者的个人信息、借阅历史记录、借阅限制等。

管理员可以针对不同的读者类型设置不同的借阅权限，确保图书馆资源的合理利用。

5. 统计和报表SQL数据库提供了强大的统计和报表功能，方便图书馆管理员进行图书馆运营效果的评估。

通过SQL查询语句，可以得到图书馆的借阅量、图书馆藏资源的流通情况等各项指标，为图书馆决策提供有力支持。

图书管理系统实验报告+源代码

图书信息管理系统课程设计：图书信息管理系统设计人员：林俊柱开发环境: eclipse数据库: sql server 2005说明：数据库里面的用户名为”sa”, 密码为：”1111”登录程序所用的用户名为: ljz ,密码为： 0000,当然，也可以使用注册功能，注册完成后使用自己的用户名和密码登录设计思路:该图书信息管理系统主要便于图书管理员管理教师的书籍借阅情况。

该程序实现的功能总共有五个板块：1、教师信息管理:包含了增加、删除、修改、查询教师信息等功能；2、图书信息管理:包含了增加、删除、修改、查询图书信息等功能；3、借书登记:登记教师借阅图书的相关信息；4、还书登记:登记教师归还图书的相关信息；5、催还:查询出并列出教师借阅图书超过期限的相关信息，以便催促教师还书.数据库的设计思路为：Teacher（读者号，姓名，性别，年龄，部门，联系方式）Book（ISBN，书名，作者，出版社，价格，类型）Borrow（读者号，ISBN，借阅日期，归还日期，办理人，归还办理人）（横线为主键，蓝色字体为外键）管理员信息表：Administrator（管理员编号，管理员密码，管理员姓名，性别，年龄，联系电话）数据库的连接：public class Dataclass {private static Connection conn = null;String driverName= "com.microsoft.sqlserver.jdbc.SQLServerDriver";String dbURL = "jdbc:sqlserver://localhost:1433;DatabaseName=Java 课程设计数据库 ";String userName="sa"; //默认用户名String userPwd="1111"; //密码//构造函数public Dataclass(){ //用于连接数库try {if (conn == null) {Class.forName(driverName);conn= DriverManager.getConnection(dbURL, userName, userPwd);}elsereturn;}catch (Exception e) { //捕获数据库连接不成功异常e.printStackTrace();}}public static ResultSet executeQuery(String sql) { //传送返回结果集的SQL语句try {if(conn==null)new Dataclass(); //调用构造函数连接数据库returnconn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR _UPDATABLE).executeQuery(sql); //返回可滚动的并发事件}catch (SQLException e) { //捕获访问数据库失败异常e.printStackTrace();return null;}}public static boolean executeUpdate(String sql) { //发送不返回结果集的SQL语句try {if(conn==null)new Dataclass(); //调用构造函数连接数据库int i = conn.createStatement().executeUpdate(sql);if(i != 0)return true;}catch (SQLException e) { //捕获访问数据库失败异常System.out.println(e.getMessage());return false; //不成功返回-1}return false;}public static void close() { //断开数据库连接方法try {conn.close();}catch (SQLException e) {e.printStackTrace();}finally{conn = null; //设置数据库连接对象为空}}}登录界面的实现：代码为：public class KCSJDL extends JFrame{JTextField textField1;JPasswordField textField2;public KCSJDL(){t ry{//

采用数据库技术生成的图书馆借阅管理系统将会极大地方便借阅者并简化图书馆管理人员和工作人员的劳动，使工作人员从繁忙、复杂的工作进入到一个简单、高效的工作中关键字：图书借阅；人员管理；图书维护。

目录1．引言随着社会信息量的与日俱增，职场竞争的日趋激烈，越来越多的人更关注知识的积累、能力的培养。

作为信息存储的主要媒体之一图书，数量、规模比以往任何时候都大的多，不论个人还是图书管理部门都需要使用方便而有效的方式来管理自己的书籍。

在计算机日益普及的今天，对个人而言若采用一套行之有效的图书管理系统来管理自己的书籍，会方便许多。

对图书管理部门而言，以前单一的手工检索已不能满足人们的要求，为了便于图书资料的管理需要有效的图书管理软件。

对于日益扩大的图书馆，查找特定的书目总是借阅者或工作人员劳神费力，有时还没有结果。

因此往往是投入了大量的人力和财力却得不到高效的管理效率。

为了缩短借阅者的等待时间，减轻工作人员的工作量，方便工作人员对它的操作，提高管理的质量和水平，做到高效、智能化管理，从而达到提高图书借阅信息管理效率的目的，采用数据库技术生成的图书馆借阅管理系统将会极大地方便借阅者并简化图书馆管理人员和工作人员的劳动，使工作人员从繁忙、复杂的工作进入到一个简单、高效的工作中。

本文以高校图书馆管理系统管理系统开发过程为背景，全文分为目录、需求分析、概要设计、逻辑设计、物理设计，以及系统的实现等全过程。

数据库图书信息管理数据库SQL语句

实验 SQL语言一、实验目的1、理解数据库以及数据表的设计；2、熟悉SQL Server2005中的数据类型；3、熟悉使用SQL语句创建和删除模式和索引；4、掌握使用SQL语句创建、修改和删除数据表；5、掌握使用SQL语句查询表中的数据；6、掌握使用SQL语句插入、修改和删除数据表中的数据；7、掌握使用SQL语句创建、删除、查询和更新视图。

二、实验内容（一）创建数据库和模式1、通过SQL语句创建图书信息管理数据库，命名为“db_Library”，数据文件和日志文件放在D盘下以自己学号和姓名命名的文件夹中，数据文件的逻辑名为db_Library_data，数据文件的操作系统名为db_Library_data.mdf，文件初始大小为10MB，最大可增加至300MB，增幅为10%；日志文件的逻辑名为db_Library_log，日志文件的操作系统名为db_Library_data.ldf，文件初始大小为5MB，最大可增加至200MB，增幅为2MB。

2、通过SQL语句在该数据库中创建模式L-C。

（二）创建和管理数据表要求为各数据表的字段选择合适的数据类型及名称；为各数据表设置相应的完整性约束条件。

1、通过SQL语句将以下数据表创建在L-C模式下：课程信息表（tb_course）——课程编号Course number 、课程名Course name 、先修课The first course 、学分credit2、通过SQL语句将以下数据表创建在该数据库的默认模式dbo下：图书类别信息表（tb_booktype)——类别编号Type number 、类别名称Category name图书信息表（tb_book）——图书编号ISBN 、类别编号Type number、书名title 、作者author、出版社BookPublic、定价BookPrice、库存数Inventory number读者信息表（tb_reader）——读者编号Reader ID 、姓名、性别、学号Student ID 、班级、系部pastern借阅信息表（tb_borrow)——图书编号、读者编号、借阅日期Borrowing date 、归还日期Return date3、通过SQL语句对读者信息表进行修改：删除系部字段、添加所在系字段。

2．上机实现。

1.问题描述背景随着图书馆规模的不断扩大，图书数量也相应的增加，有关图书的各种信息量也成倍增加，面对着庞大的信息量，传统的人工方式管理会导致图书馆管理上的混乱，人力与物力过多浪费，图书馆管理费用的增加，从而使图书馆的负担过重，影响整个图书馆的运作和控制管理，因此，必须制定一套合理、有效，规范和实用的图书管理系统，对图书资料进行集中统一的管理。

另一方面，IT产业和Internet获得了飞速发展，计算机应用已渗透到了各个领域，引起信息管理的革命，实现了信息的自动化处理，提高了处理的及时性和正确性。

提高图书管理工作效率，作到信息的规范管理，科学统计和快速查询，让图书馆更好的为学校，社会服务。

数据需求图书馆管理信息系统需要完成功能主要有：1. 读者基本信息的输入，包括借书证编号、读者姓名、读者性别。

2．读者基本信息的查询、修改，包括读者借书证编号、读者姓名、读者性别等。

3．书籍类别标准的制定、类别信息的输入，包括类别编号、类别名称。

4．书籍类别信息的查询、修改，包括类别编号、类别名称。

5．书籍库存信息的输入，包括书籍编号、书籍名称、书籍类别、作者姓名、出版社名称、出版日期、登记日期。

6．书籍库存信息的查询，修改，包括书籍编号、书籍名称、书籍类别、作者姓名、出版社名称、出版日期登记日期等。

7．借书信息的输入，包括读者借书证编号、书籍编号、借书日期。

8．借书信息的查询、修改，包括借书证编号、读者编号、读者姓名、书籍编号、书籍名称、借书日期等。

9．还书信息的输入，包括借书证编号、书籍编号、还书日期。

10．还书信息的查询和修改，包括还书读者借书证编号、读者姓名、书籍编号、书籍名称、借书日期、还书日期等。

11．超期还书罚款输入，还书超出期限包括超出期限还书的读者借书证号，书籍编号，罚款金额。

12．超期还书罚款查询，删除，包括读者借书证编号、读者姓名、书籍编号、书籍名称，罚款金额等关系模式(一)书籍类别（种类编号，种类名称）(二)读者（借书证编号，读者姓名，读者性别，读者种类，登记时期）(三)书籍（书籍编号，书籍名称，书籍类别，书记作者，出版社名称，出版日期，登记日期）(四)借阅（借书证编号，书籍编号，读者借书时间）(五)还书（借书证编号，书籍编号，读者还书时间）(六)罚款（借书证编号，读者姓名，借书证编号，书籍编号，读者借书时间）以上通过关系代数方法的进行运算得到所需要的结果，在实验结果中可以看到。

２.方案图表设计E-R图根据1）所要实现的功能设计，可能建立它们之间的关系，进而实现逻辑结构功能。

图书管理信息系统可以划分的实体有：书籍类别信息实体、读者信息实体、书籍信息实体、借阅记录信息实体，归还记录信息实体。

用E-R图一一描述这些实体。
