Library management system is an indispensable part of some units. Books are indispensable spiritual food for human beings, especially for some schools. Therefore, the library management system should be able to provide users with sufficient information and fast query methods. However, people have always used traditional manual methods to manage books, journals, bound volumes of test papers, etc. This management method has many shortcomings, such as low efficiency and poor confidentiality. In addition, over time, a large amount of files and data will be generated. This brings a lot of difficulties to search, update and maintenance.
With the continuous improvement of science and technology, computer science has become increasingly mature, and its powerful functions have been deeply understood by people. It has entered various fields of human society and plays an increasingly important role. As part of computer applications, using computers to manage book resource information has advantages that manual management cannot match. For example: fast retrieval, convenient search, high reliability, large storage capacity, good confidentiality, long life, and low cost. wait. These advantages can greatly improve the efficiency of library management, and are also important conditions for scientific and formal management of enterprises and schools to integrate with the world.
Therefore, it has become very necessary to develop such a set of management software. In the following chapters, we will take the development of a library management system as an example to talk about its development process and the problems involved and their solutions.
Library management system is a typical information management system (MIS). Its development mainly includes the establishment and maintenance of back-end database and the development of front-end applications. For the former, it is required to establish a library with strong data consistency and integrity and good data security. For the latter, the application is required to be fully functional and easy to use.
After analyzing this situation, we used Microsoft's VISUAL BASIC development tools and various object-oriented development tools provided by it, especially the data window, an intelligent object that can conveniently and simply manipulate the database. First, we established it in a short time System application prototype, and then iterate requirements on the initial prototype system, and continuously revise and improve until a feasible system that is satisfactory to users is formed.
