Design And Realization Of Community Library Management System

Along with the social information increase steadily, Book as one of the main media which can save information, the quantity and the scale of the book are much more than former. In spite of personal, the book management sections all need to use one convenient and valid way to manage his books. Now, more and more computer is widely used in each realm. It is more convenient if you adopt a set of valid book management system to manage the books. A long with the persistent manifold of the amount of the book in each community library and the persistent extend of library's scale, it is very difficult to manage this huge system. Because the instance of book are changed at any moment, so we must to manage the book dynamic, it is very complicated for a library manager. In order to set the manager free out from the heavy work, and let the manager can easily manage all the books with software well and truly; it is urgent to develop the software about library management system. It is also the important meaning and research aims that this thesis is choused.As a software engineering master, I attend the practice of development and test in library management system, put my learning theory into practice to meet current needs and present operation enhances my wisdom. I learn many from this project participated in and gain many feelings, which will never be forgot, my thesis will illustrate some knowledge met in this project.I have carried on the research of the following key technology mainly about this subject:1. Introduce the key technology about the task. Include the database programme technology in Delphi and the application of SQL used in Delphi. the research about the structure and empolder methodological of data base application system; research about middleware and on-line transaction processing of Database and so on.2.Analyse the library management information system.Analyse the system need satisfy the application requirement from three aspect, there borrower, library missionary and library manager. Analyse the main flow; include book circulation, inquire about book and system manage ,and so on.3.Design the system.Include design the main module in the system, design the main interface and the main function, design the conception and the logic of the system database.4.Implement the system main function.Include borrow and return book, query the information about book and borrower, maintenance the information about book and borrower, and so on.The whole purpose of this article is to discuss the key technique of the topic research as well as the design and development of the library management system.
