I have a rather big SQLite file in my GIT repository and I was wondering why my total repository size was not growing that much but instead, was even smaller than my SQLite-.db-file. Turns out, GIT compresses the repository by default. A quick check on my .db-file also indicates this, since zipping the .db-file resulted in a zip-archive which was only ~20% the size of the .db-file.

So, at least with the default settings, it doesn't look like SQLite is storing the data in a compressed way. However, regardless of that, it might be fine to add a big SQLite file to a GIT repository, since GIT performs compression automatically.
