Version Control ? Mengatur file sharing untuk Concurrent Development Keeps track of changes with Version Control SubVersion (SVN) is a version control systemhttp://subversion.tigris.org/
Subversion 7 Subversion is the free/open-source version control system Manages files and directories over time. Remember every change even made to files and directories. Allows to recover older version of the code or examine the history of how your data changed. Collaborative editing and sharing of data (source code).
Concurrent Development Server holds all original files of a project Gives out copies to participants (clients) Participants modify their copies Submit their changes to server Automatically merges changes into original files. Huge! Conflicts only occur when modifications are done –by more then one participant –at the same location in their respective copies. –Then participants have to manually resolve such conflicts. Rare! Powerful edit and merge tools help make this task easy
Version Control SVN keeps log of any changes made to any file. Ever! Also keeps copies of those changes. For ever! Participants can go back and receive older versions of a file or even an older version of an entire project state Example: The current version number of our project in SVN is #5 In the future you can always load the project exactly as it is today by requesting project version #5; et voila you can run an age old demo!
How to use SVN (in a nutshell) Checkout: receives a copy of an entire project from the SVN server (source files, project & make files, resource files, etc.) Update: receives copies of individual files or folders on the server and merges them with your current copy (locally) Commit: sends an updated file (your local copy) to the SVN server where it is incorporated into the original project database; a new version number is assigned not the entire project Add: notifies SVN of a new file or folder that needs to be added to the existing project (only if SVN is aware of a file, can you commit the file)

Further Considerations before doing a commit you MUST do an UPDATE (and resolve any possible conflicts) BEFORE you COMMIT your copy to add a new file or folder you need to use ADD and then COMMIT if you want to get rid of a file, you need to delete it in your local folder and then COMMIT the folder
Further Considerations (cont.) Make sure to UPDATE REGULARLY otherwise you will have lots of conflicts SVN will not help you if you do not COMMIT REGULARLY If you add lots of new stuff, make sure to COMMIT EVERYTING
SVN vs. CVS Functional replacement for CVS Directory versioning (renames and moves) Atomic commits (all or nothing) Faster network access (binary diffs) Requires less network access
