Apache Subversion (SVN) is an open source version control system that allows software developers to work collaboratively and track revisions over time. It retains a full history of changes, supports merging of branches, and has language bindings for many programming languages. SVN allows developers to update their local files, commit changes, and resolve conflicts when merging revisions. It is implemented through both server and client-side software that manages repositories of file revisions.

2. INTRODUCTION

 A tree conflict occurs when a
developer
moved/renamed/deleted a file
or folder, which another
developer either also has
moved/renamed/deleted or just
modified

14. Rules oN using SVN
 Carefully test your code before committing
 Always commit only the individual files you modified, not the entire directory
 When adding new files to the existing source code, always perform SVN Add and
then SVN Commit

15. LIMITAtions of svn
 Locking: Subversion currently has no support for file locking, to prevent more
than one person from working on single file.
 Subversion does not store the modification times of files.
 Subversion stores additional copies of data on the local machine, which can
become an issue with very large projects or files,
