The setup and use of SVN

SVN is a subversion abbreviation, is an open source version control system, compared to RCS, CVS, it uses a branch management system, its design goal is to replace CVS. Many version control services on the Internet have migrated from CVs to subversion.
1. Performance improvement. SVN regardless of whether the file is text or binary type, the internal is a binary diff comparison algorithm to represent the update part of the file. This means that all files are stored in a different form in the file library. and the transmission on the network, is the small file difference part. This also makes branching, tagging, merging, and so on can be done very quickly.
2. The organization of the directory is more convenient to manage. SVN does not only version-track files, but also version-track directories. As a result, the directory structure can be modified at any time according to the needs of the project, and the existing directory can be moved to a new place.

3. Ensure the integrity of the submission operation. SVN handles the commit operation in a manner similar to that of a database transaction, either all successful or all invalid to ensure atomicity.
