Research And Implement Of Resource Management Subsystem In Web-based Cooperative Editing System

With the continuous development of information technology,information technology has penetrated into every industry,it is important to work together and communicate between each other in real-time.Web-based Real-time Cooperative Edit System(WRCES)has been developed to solve the existing text editing system inefficient and complicated issues.Users only need to use their browser to collaboratively edit the same document,and they can immediately see the results of other users,it also supports a variety of smart devices,which greatly improves the work efficiency.However,due to the way of information transmission and information has changed greatly,The WRCES is very different from the traditional model of collaborative resource management,which is particularly evident in documents and users management.At the same time,the WRCES require a higher real-time and consistency,in order to ensure that the information state between multiple users can be synchronized in real time.Aiming at the problem,with the domestic and international research,this paper put forward a complete solution of resource management in WRCES,which manage user privileges by user group and role assignments,and format the transmitting data to reduce the amount,and analyze the conflict of user's operation to implement the consistency maintenance problems using Operation Transformation.This paper analyze the design principles and models of resource management subsystem,and it is divided into user management module,data synchronization module and data storage module implement by Node.js and WebSocket.The resource management subsystem also inplement session management,document storage,user's opreation record and accessibility features that assist other subsystem.First,This paper research the features of WRCES,and analyze the functional requirement of resource management subsystem.Then summarize the architecture and make a detailed presentation on technical route and key technology which use to implement the subsystem.Finally,the paper test the resource management subsystem to verify it's correctness and practicality.
