使用subversion for PHP的集成开发

We are two in a team working on the same project. i am on MAC and the other one is on PC. i have never used SVN before. googling about the SVN gave me basic understanding about svn. and what i understood is there should be subversion installed in client machine (i do not know which client, i assume there are many like versions and cornerstone for mac, tortoise for windows etc. and i require a repository where i will host the centralized version of the application. the client will get the copy of codes or files where they can commit the changes to repository (main application). which can be undone if required. however what i don't understand is, as our PHP code uses database(mysql in my case) how is it managed by SVN client?We are two in a team working on the same projec
