First of all, it is very important to determine the type of school (university library, vocational and technical school library or primary and secondary school library). Due to the different scale of the school, the functional modules that need to be designed by the library management system will be different.

After defining the types of schools, we began to consider the functions of the management system. In this way, we must have a profound and in-depth understanding of the whole management process of the library, so as to design various management modules, such as: interview module, cataloging module, circulation module, system management module and so on. And each specific module should write detailed process design and function realization design scheme. It is best to have practical application cases as supporting arguments for the paper.
