I built a system in 2008 that would let me design a database and the automatically generate an entire admin backend, granular ACL rules for different users and roles, related records and interactive table fields like toggle switches. It wasn’t statically generated so it easily adapted to changes in the database over time too. Could also swap out the UI theme per customer. Among other things.
Called it The Intersect because I was and still am a huge fan of “Chuck”.
It sped up my client projects so much that it killed my hourly income.
Now there are lots of systems that do this type of thing, but at the time I was very proud of that system. It was nice to be able to focus on web project from a purely data design back approach.
