We created a Seeker that translates OCL to SQL for searching databases of any size. We look at derivations, constraints, and validation rules.

To make your experience smooth, we set the main tags mentioned in the video in the right-bar menu of this mini-player. Choose an interesting subtitle from the list and immediately get to the exact theme navigation item in the video. Now you can pick any topic on which to be instructed without watching the whole video.
