Research And Analysis Of China Telecom 's Winding System

This paper introduces the present situation of home-school with education and information behind, and detailed design of China Telecom wing school system in the province education information technology projects as the background.Firstly it explained the development of educational information in the Wenshan and proposed with the home-school education highlighted the problems at this stage,it requires information systems to assist in solving,and presented research wing-school system to solve these problems.finally,it elaborated I undertaken major work in the project.This paper analyze and design China Telecom wing school system by structured approach.At frist it lists unit and departmental organization which use of the China Telecom wing school system in business analysis,it analyze the existing business problems and business people work conten and analysis of the home-school communication, interactive teaching, school attendance, learning resource sharing existing business processes by lanes diagram,it optimize business process for the four existing business processes by lanes diagram too;At frist it mainly analyzes duties and functions of the system four roles in analysis of the system function,then it analyzes detailed data flow of home-school communication, interactive teaching, school attendance, resource sharing, basic information management, systems management five sub-function module by three layer of DFD diagram,and each data stream, storing, processing is described in detail.Finally it designs functional block diagram of the overall system and functional block diagram of the sub-function module by H diagram,it briefly each sub-module functions realized;This paper analyzes the relationship between each entity of the system by E-R diagram,then it design detailed data of database table structure. The end of the paper summarizes the wing school system to solve the home-school education brings the convenience and timeliness of effectiveness and points out the shortcomings of the existence of several systems.Finally,it looks forward to the next step of operations and system optimization.
