Library management system

Abstract

The invention provides a library management system. The library management system comprises a database, an application logic component and a connection object, wherein the database stores the user information, book information and borrowing information of a library and is a relational database; the application logic component comprises a user module, a book information module and a borrowing information module; the user module manages the user information of the library; the book information module manages the book information of the library; the borrowing information module manages the borrowing information of the books in the library; when the modules in the application logic component access the database, the connection object is used to realize accessing; and every time the application logic component sends a request to access the database, the connection object establishes a connection between the database and the application logic component and cancels the connection after the accessing. In the library management system, the data storage part and logic function part of the database are separated and can be modified and upgraded independently, thus the use convenience and expansibility can be increased.

Description

technical field [0001] The invention relates to database technology, in particular to a library management system. Background technique [0002] The current book management method of the library is to carry out the cataloging, collection, query, circulation and other work of books completely in a manual way. [0003] In order to make full use of the convenience brought by the computer system, there are also library management systems that have been developed. These library management systems are based on computer technology and realize the functions of cataloging, collection, circulation, readers, query, and system maintenance. The system completes the overall function. The system adjusts and divides the subsystems. Cataloging includes simple numbering of books; operations such as adding, modifying, and deleting collections can be performed for collections; circulation can realize various operations such as borrowing, returning, and renewing books; readers can implement var...

AI Technical Summary

Problems solved by technology

When the library uses these systems, it does not feel the improvement of work efficiency. Over time, it lacks interest in the library management information system and is unwilling to make more investment.

[0007] 2) Complicated operation

However, if the system does not consider the actual situation of users, the interface is not friendly enough, and the operation is too complicated, it will make these novices who have just learned computers feel inconvenient in operation

If this inconvenience continues, it will make the operator feel rebellious, which will affect the normal use of the entire system.

In particular, the introduction of a lot of computer expertise has increased the difficulty of using the system.

[0009] 3) Slow upgrade

[0010] In the past 10 years, computer hardware, software, and network equipment have been upgraded very quickly. If the upgrade of the management information system cannot be synchronized with the supporting platform, many problems will occur in the application of the system, and even the entire system will be paralyzed.

Due to the huge amount of data involved in the upgrade of the library management system, it often hinders the progress of the system upgrade
