Just one day. That’s how much time the students of Software University had between the two lectures I delivered for them. During the second one, we talked about transactions. We again had 4 hours in front of us, so we started with the basics, but ended in the world of isolation levels and update conflicts. We also touched on what problems come when using locks and of course they know now what ACID means(because I told them they are going to be asked on their interviews about this!). As last time – here is the video, screen capture and slide deck. Almost everything is again in Bulgarian though.
