From my experience in enterprise business intelligence, absolutely yes but more for the tracking rather than the ability to roll back changes. Data lineage is an important concept and is extremely valuable from a compliance perspective. The key would be can your system integrate with existing data sources?

You'll also likely be going up against Informatica if you want to play in the Enterprise space. That said, I'm also interested in a solution like yours as we're rolling out our own automation system but need to keep track of things for compliance reasons.

Would be happy to have a chat.

What sort of structured data are we talking about?

If you format an XML or JSON file with one field per line (or just use YAML) git itself should fit the bill perfectly.

Now, I do see lots of room for a git-like tool targeted at specific existing binary file formats. Microsoft Office and Photoshop files come to mind off the top of my head. (I believe that such tools already exist for those particular formats, but they're expensive and currently have low adoption.)

Any kind. JSON or XML could be input. Or things like SQL or protobufs.

Git itself doesn't work well for large-scale data (https://help.github.com/articles/what-is-my-disk-quota/). I'm thinking terabyte or petabyte datasets.

Relevant: GitHub Large File Storage https://git-lfs.github.com/

On paying for this. When data operations are built around pipelines, it's often easier to re-run the pipeline or restore a snapshot. Which requires a good server, but not a service. So before paying, I'd check why the new tool is better.

Yeah, except that this is not really built into Git. You can't get detailed differences or merge differences in these large files. They are basically opaque blobs as far as Git is concerned.

I would use it for storing and tracking specifications if this is a possible usage. In regulatory compliance, there is always a need to know what the specification was at some point in time.

However, any system would have to be available on a private internal network for most places.

What advantage would this have over using something like a log table? Or a few SQL(or whatever) commands?

Or something like Datomic (http://www.datomic.com/)

The Dat project?...
