Now a day’s subversion is very much popular among the developers. More than one person can work on same file by using subversion. The big benefit of using subversion is the ability to merge changes on the working file so that more than one developer can work on the same file. With Subversion each developer has its own working copy of repository. We do changes on our working copy and commits on the repository .When more than one person working on same file and using SVN then by using the update the changes done by one person can be merges on our working copy so that no conflicts arise. Conflicts are arise only when two developer made changes on same line. These can be solved manually but there is very rare chances for conflicts .So with subversion on the same project more than one developer across different countries can work .
