How to Create a Custom Sourcing SQL Query

We've implemented relations to a certain extent. Not everything all the way because we think it's an overly complex problem but we've implemented some stuff. And also we've taken trouble to really implement a lot of more complex crud scenarios. Some examples I can throw out are computed fields which are not physically stored in database but are computed on the fly where they go back to the front end. There are other examples and there's also obviously escape hatches. If you want to use raw SQL you don't have to write your own end point. You can still use the remote end points and then just translate your filter to raw SQS filters somewhere in these escape hatcheswe've prepared.
