A grouping-based concurrent locking method for collaborative editing

Abstract

The invention relates to a grouping-based concurrent locking method for collaborative editing, belonging to the field of collaborative editing in computer science. The invention aims at solving the problem of mutual exclusion and intra-group cooperation among N groups of multi-users in cooperative editing, reducing collision waiting time and improving system efficiency on the premise of ensuring independence and integrity of each group of editors as much as possible. The invention provides a calculation method of user priority coefficient and cooperation index and four concurrent locking strategies. When a user joins a system to initiate an editing activity, a grouping in which the user is located is first judged, a new group is established if there is no grouping, an existing grouping isadded to the group, and a locking application area is then processed. At that time of conflict, different solution are adopted for conflict with members of the same group and conflicts with other members of the group, so as to strengthen cooperation in the group and improve concurrency of the cooperative edit system. The invention is widely applicable to application scenes of collaborative processing graphics documents and the like for collaborative editing in a two-dimensional cooperative space.

Description

technical field [0001] The invention relates to a group-based collaborative editing concurrent locking method, in particular to a concurrent control method in multi-user N group collaborative editing, and belongs to the field of collaborative editing in computer science. Background technique [0002] With the development of information and computer technology, people's living and working methods are increasingly characterized by group, interaction, distribution and collaboration. The real-time collaborative editing system is an emerging research field born on the background of it, and it is an important application direction in computer-supported collaborative work [1-3] . Most of the research on collaborative editing systems takes a single user as the basic unit, but in real life, there are many users forming a group, and there are cases of collaborative editing within and between groups. In this case, multiple groups of users simultaneously Issue collaborative requiremen...

Problems solved by technology

[0015] The purpose of the present invention is to propose a group-based collaborative editing concurrent locking method to solve the concurrency control problem in multi-user N group collaborative editing

Based on the fact that existing concurrency control methods cannot effectively solve the current situation that there are multiple groups of users simultaneously issuing collaborative demands, the present invention proposes a concurrent locking method for N groups of multi-users according to the different needs of members within and between groups when performing editing operations; at the same time Using variable locking granularity, it can not only meet the editing needs of users, but also ensure the editing efficiency of the entire system to the greatest extent
