The only thing missing in this series is a video where you actually put these things into practice and navigate around an actual DBMS like MySQL or even MS Access (for simplicity) and show where and how all these concepts apply.

I seriously sat through these lectures and slayed a few dragons here at work, as a total amateur. I feel more like a pro now. Thank you for posting this.

Quick question: Dirty read definition: When a transaction by user A reads modified data by user B that is not commited in the DB. If transaction by user A can read data that is modified by user B, doesn't that mean the data is committed?

so at 20min into the video, if they had preformed the action of reducing the inventory as a math function instead of doing the math themselves then rewriting whats there could it have worked?

Sir we only started transaction OT2 and we finished with no object that's the transaction in log table. May you give us explanations about that please. Thank you

Thank you for the series of lessons. I just have one question regarding this video. Why a role can have 0 permissions assigned? (part 1:09:20) isn't it necessary for a role to have at least one permission to exist?
@marianos41015 жыл бұрын
Remember that in cardinalities, 0 is an "optional" number of entity instances. So he could simply set a One-to-Many relationship, but have in mind that there might be some cases where a role may have 0 permissions. Imagine, for some reason, that you insert a new entity called "potential candidates" for a new job role, so you enter this new entity, but let it have 0 permissions, because there shouldn't be any permissions granted to modify data to potential new users. But I'm just a brand new Database learner, so I sticked to my poor knowledge. Hope it helps.
