Requirement Analysis on Network Teaching Management System

摘要

Network teaching is to use computer equipment and Internet technology in the virtual space, through a certain method to implement the teaching method on the network, the perfection of the network teaching system can directly replace the traditional teaching method in the whole process of teaching. In order to solve the problem of system development, this paper carries out the demand analysis. First, the use of data flow graph technology, depicting information flow and data from the input to the output of the process of transformation; and then, the use of data dictionary technology, defining the relevant elements of the data flow diagram; finally, the use of tree structure diagram is represented by the administrator subsystem, teacher subsystem and student subsystem structure of the system. The requirement analysis system design the bridge of analysis and software, has laid a foundation for the system development.
