SVN full name Subversion, that is, version control system. SVN, like CVS, is a cross platform software that supports most common operating systems. As an open source version control system, Subversion manages data that changes over time. These data are placed in a central data archive (repository). The archive is like an ordinary file server, but it will remember the changes of each file. In this way, you can restore the file to the old version, or browse the changing history of the file.
