We've been using it on a project to aggregate clinical trial data from many different sources (https://opentrials.net) and it has been great!

It allows researchers (not necessarily devs, usually medical doctors) to peek our raw data, and it's a great excuse for them to learn at least the basics of SQL. The response has been great.

We also use it to do some small data checks on the data quality, with alerts sent to our Slack.

Highly recommended.
