Research on concurrency control algorithm for real-time collaborative editing systems

Abstract

Real-time collaborative editing systems are important groupware tools in the computer supported cooperative work (CSCW) field. They support geographically dispersed users to edit shared files, graphics, etc. simultaneously. Currently popular real-time collaborative editing systems mostly use plain text data for edit and synchronization, and the corresponding operations are deleting, adding or modifying characters. The data acquisition system's metadata in this article is the module, such as deleting, adding or modifying a certain question. On the basis of differential synchronization algorithms and generic operation transformation (GOT) algorithm, this paper proposes a new concurrency control algorithm differential synchronization and generic operation transformation control algorithm (DSGOT).
