I used to work on a document workflow system, and it basically implemented a half-baked version control system for documents; using a database for versioning information and a filestore for the files. It was a lot of code, and hard to maintain. There were all sorts of bugs with locking and similar things, you name it.

If I had to rewrite it from scratch, I would seriously consider using git as my data store.

It occurred to me that I haven't read much about git (and most version control systems) being used in application implementations, as versioned data stores.

What applications use git, or another VCS, behind the scenes for storing and versioning data?

This appears to have been done via both Ruby and Python some time ago. So it's entirely possible to use it as such.

I use git (also mercurial, svn, etc can be used if you prefer) as datastore and history for base code and for separate branches of almost all of my projects. It is fairly simple to use, and there are many tutorials for it.

It keeps a cache of all your previous states of data, called "commits" and is fairly simple to view all of them, either by command line or one of the bazillion gui clients for it.

Git was originally written for the gnu linux kernel, and of course is still in use for that. There are many links from wikipedia to sites that are for free hosting of git repos.

As @world-engineer mentioned, Ruby, Python, as well as many web apps (Django, Joomla, Drupal, etc) are currently using git for their team developments.

A stackoverflow question was asked here about git as well: git-where-can-i-find-simple-tutorial-about-how-to-use-git

Hi CometSong, I think the OP is asking about using git as a data store in his application (ie instead of a database). He is not talking about git as a source code version control system in this context. –  MattDavey Feb 28 '13 at 9:07
    
True on the file storage part. Good point. I was thinking only on his "versioning information" piece. –  Cometsong Feb 28 '13 at 9:54
