With the development of human society, the demand for knowledge is increasing. In this situation, books have gradually become the main way for people to acquire and increase knowledge, and libraries naturally occupy a certain position in people's lives. How to manage the library scientifically is not only related to the convenience of readers' knowledge, but also related to the development of the library. Therefore, it is very necessary to develop a perfect library management system.
Management information system (MIS) is a marginal, comprehensive and systematic interdisciplinary subject between information theory, economic management theory, statistics, operational research and computer science. It comes into being and develops with the development of management science, information technology and computer technology.
Book management system is a typical information management system, and its development mainly includes the establishment and maintenance of background database and the development of front-end application programs. For the former, it requires the consistency and integrity of data, while for the latter, it requires the integrity and ease of use of the application. Based on the above considerations, this system mainly uses PowerBuilder 8 as the front-end application development tool, Adaptive Server Anywhere 7 as the background database, and WINDOWS as the system platform to develop the book management system. In addition, the book management system adopts the idea and method of software engineering, generally adopts the structured life method for system analysis and design, and the steps of system realization adopt the prototype method and the object-oriented method.
1 development method of management information system
The development methods of management information system include life cycle method, prototype method and object-oriented development method.
Life cycle method is a widely used and mature management system development method developed in 1960s. Its basic idea is to divide the system development work into several stages from beginning to end, and each stage has clear tasks. After the system development is completed, it does not mean the end of the life cycle, but the beginning of modifying and reconstructing the system according to the needs of the organization.
