What is version control?

Revision control is a software engineering technique used during development to manage the history of changes made to files, directories, or projects. It can be easily viewed and backed up to restore previous versions.

Version control classification

1. Local version control

2. Centralized version controlSVN

All version data is stored on the server, and users only have the version they have synchronized before. If they are not connected to the Internet, users cannot see the historical version, switch version verification issues, or work in different branches. Also, all the data is kept on a single server, and there is a high risk that the server will get corrupted and all the data will be lost.

Distributed version controlGit

All version repositories are fully synchronized to each user locally, so that all version history can be viewed locally, can be submitted offline locally, and can be pushed to the appropriate server or other users when connected to the network. Because each user there is saved are all version data, as long as there is no problem with a user’s equipment can recover all the data, not because of server damage or network problems, cause can not work! Disadvantages: increased the occupation of local storage space, afraid of direct code run.
