2.2 Data description (data flow diagram + data dictionary)
Under the current librarymanagement business processes, data flow diagram first source point and end point are selected for students, so you can get the basic system model library management system, shown in Figure 2.2

In this way, there are many shortcomings, such as low efficiency, poor security and more cumbersome. In addition, as more and more books and materials, which will greatly increase the workload, which will increase the workload management and labor intensity of library materials, books and materials that will find, update and maintain information have brought a lot of difficulties. Detailed investigation in all types of colleges and universities, there are still a considerable number of library management units on the basis of manual management. This management system can not adapt to the times, and its management will waste a lot of manpower and material resources. With the continuous improvement of science and technology, the traditional manual management methods must be a computer-based information management instead.
