1.1 Analysis of basic requirements function points
The main goal of the book borrowing management system is to simplify the existing manual management, through scientific computer management of the book borrowing management, improve work efficiency, and realize daily management information and paperless.
1) System users are mainly divided into two categories: a. Administrator user category (equivalent to a super user with various operation permissions) b. Ordinary user category. The system chooses to log in to different pages for subsequent operations according to different identities on the login page.
2) The main functions of administrator users: a. Management functions: user management, book management (book category management, book information management), reader management (reader category management, reader information management), borrowing record management, system management (logout, Exit); b. Statistics function: statistics of the most popular book categories, statistics of the most popular books, statistics of active readers, statistics of untrustworthy readers.
3) The main functions of ordinary users: a. Management function: book borrowing management (borrowing books, returning books), password modification, system management (logout, exit); b. Query function: querying readers’ borrowing status, querying book borrowing status.
4) System performance: adapt to the actual library management needs, timely update of information, efficient and accurate data query, and improve the management efficiency of staff.
5) System input: user name, user password, various information of books, various information of readers, etc.
1.2 Analysis of system operating conditions
This software system requires at least one computer as a server, and requires that the computer is equipped with Microsoft Visual Studio and SQL Server. The detailed system requirements are as follows:
·Windows XP or Windows 7 and above
·Microsoft Visual Studio 2005 and above
·SQL Server 2008 or higher version database server.
2. System design
2.1 System function module design
The design of the system includes two aspects: system function module design and database design. This article will introduce the overall module design and database design of the system. The specific function modules will introduce the main interface of administrator operation, book borrowing function, book return function and borrowing record Delete function. The overall module diagram of this system is given below:
2.2 Administrator function module
The specific function of this module is to query and manage information such as ordinary users, book information, reader information and book borrowing conditions, including system management, user management, book management, reader management, data statistics and data management.
1. User management module: Under this module, the administrator user mainly adds, deletes and resets the password of ordinary users.
2. Book management module: This module contains two sub-modules: book category management and book information management. Book category management includes adding book categories, modifying book categories and querying book categories; book information management includes adding book information, modifying book information, querying book information, and disposing of scrapped books.
3. Reader management module: This module contains two sub-modules: reader category management and reader information management. Reader category management includes adding reader categories and checking and modifying reader categories; reader information management includes adding reader information, viewing reader information, checking and modifying reader information, and deleting reader information.
4. Data statistics module: This module mainly counts the readers' borrowing situation within a period of time, including statistics on the most popular book categories, statistics on the most popular books, statistics on active readers, and statistics on untrustworthy readers.
Data management module: This module is for the administrator to delete the readers' borrowing status (returned books) for a period of time.
System Management: This module includes logout and exit.
The overall design of the administrator module is as follows:
2.3 Common user function module
The specific function of this module is to query and manage readers' book borrowing, book borrowing status, personal password and other information, including system management, book borrowing, borrowing status query and password modification and other functions.
1. Book borrowing module: This module contains two functions: book borrowing and returning books.
2. Borrowing situation inquiry module: This module contains two functions: readers' borrowing situation inquiry and book borrowing situation inquiry.
3. Password modification module: This module is generally used to modify users to modify ordinary user passwords.
4. System Management: This module includes logout and exit.
The overall design of the common user module is as follows:
3. Database design
According to demand analysis, a basic book borrowing management system database roughly includes 6 tables: user information table ( Manager ), book category table ( BookCategory ), book information table ( BookList ), reader category table ( ReaderCategory ), reader information table ( Reader ), borrowing information table ( BookLendList ). The data information of the corresponding sub-function modules are stored separately, and the tables are related to each other, and the data is operated in a unified manner. The ER diagram of the database design of this system is given below :

Extraction code: 4kut[Note]: Some configurations in the code need to be filled in according to your actual situation. For example: Line 30 in the Login.cs file, (string connstring = "Data Source = .;Initial Catalog = Library;User ID= sa;Pwd=123456";), database related information needs to be set by yourself, other files are similar. I use SQL Server authentication. If you use Windows authentication, please find a solution by yourself (very simple implementation).
