Cloud file multi-branch version management method and device

Abstract

The invention discloses a cloud file multi-branch version management method. The method comprises the following steps of storing files in a cloud, storing and managing logic files under an engineeringproject and hierarchical relationships and corresponding permission inheritance relationships of the logic files by adopting a relational database, and storing physical files under the engineering project by adopting a distributed object storage technology; allocating a unique file ID, namely File Id, to each file, and performing single file version management when each file version has a globally unique version ID, namely Revision Id; and performing multi-branch version management of the engineering project based on the mode. The method is advantaged in that logical and physical storage separation can be realized, file redundancy in a project version creation process is reduced, creation and deletion of project versions can be performed in real time in a lightweight manner, and multi-branch project version creation and combination and project backtracking are supported.

Description

technical field [0001] The invention relates to the field of building informatization, in particular to a method and device for multi-branch version management of cloud files. Background technique [0002] In the construction industry, any design and construction project will produce many 2D drawing files and a large number of 3D models by specialty and floor. Under the cooperation of multiple participants in the project, not only the number of files related to these projects is large, but the file update and version iteration are also very fast. At the same time, for a design and construction project, at the staged time nodes, the sub-model files and sub-model files are related to each other, and can be finally integrated into a complete professional 3D model for BIM business use. In the construction industry, the version control of a single design model file is not very important. Instead, it is important to carry out unified large-scale version control for all files in t...

AI Technical Summary

Problems solved by technology

[0010] (1) The number of files and the occupied disk space increase, and each additional version will add a copy of all the files contained in the project at that time, even if only a small number of files in the project were modified at that time;

[0011] (2) It takes a long time to generate a new project version, because each copy will involve all files of the entire project;

[0012] (3) The version update information of the same file between different project versions is lost, and the source file modification information cannot be tracked
