I do this, more or less, for my small law firm. Employee and client information are stored in Recfiles and accessed with GNU Recutils. Adding or changing is a pull request, and all sorts of GitHub actions run. Works pretty well!
Wat, how have I never heard of this! Very cool. Do you have any insights you could share on your own setup, what worked well and what didn't? Are you just storing information in plaintext, or do you use some visualization libraries to make consuming the information a bit easier as well? Very curious about your setup.
beyond the source controlled database, is it doing the same as what the article describes? ie enforces requirements etc
