Cocurrent control method for band collision detection based on mark and state vector

Abstract

The present invention relates to a method of computer supported cooperative working (CSCW) technology field, in particular, it relates to an application system which can be used for cooperatively editing and supporting physical-distributed several cooperators and simultaneously editing same document, and relates to a concurrency control method of tape collision detection based on mark and state vector, and said method can solve the consistency problem of collision operation. Said invented equipment is formed from input equipment, output equipment, processor module and interconnected net hardware environment.

Description

technical field [0001] The present invention relates to the technical field of computer-supported collaborative work (CSCW), in particular to an application system for collaborative editing that supports physically distributed multiple collaborators to edit the same document at the same time, and is used to ensure consistency when operations conflict Concurrency control device with conflict detection based on marker and state vector and its concurrency control method. Background technique [0002] Collaborative editing supports multiple physically distributed collaborators to edit the same document at the same time, which is an important class of Computer Supported Collaborative Work (CSCW) application systems. Collaborative editing is a typical distributed application system, which not only requires fast response speed of user operations, but also usually has the following characteristics: there is no limit to the number of collaborative users who can operate at the same ti...

Problems solved by technology

This method is easy to understand, and the algorithm design is relatively intuitive, but it needs to add an operation context when transmitting operation information. As the number of operands increases, the content of the operation context will become more and more, resulting in the continuous increase of the length of the network transmission packet and increasing the network load.

Later, someone proposed a "document annotation method with state vector", but this method did not propose a feasible solution on how to implement it, and at the same time, there was no conflict detection and processing, and the consistency of operation conflicts could not be guaranteed.
