Part 5 Searching in databases

From MDrivenWiki

We create a seeker that translates ocl to sql for searching in databases of any size. We look at derivations, constraints and validation rules.

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