UML Class and Object Diagrams | Association vs. Aggregation vs. Composition | Geekific

Class diagrams and object diagrams are the main focus of this video. Additionally, while going over the basic concepts of class diagrams we attempt to cover and define: association, aggregation and composition.

Correction: At the very end (9:20) in Object Diagrams, the direction of the arrow between the Account and its Sub-Accounts should be exactly the way it was in Class Diagrams. Sorry about that!

I have been trying to understand where to use associations by watching tutorials for an hour and 10' now. Finally I understand. Thank you!

Best explanation I've heard on this topic. I don't think ever really understood it until now.

10 minutes of effective knowledge. Thanks to you and YouTube algo for bringing your videos to me which keeps me updated with these information.

The video clearly explained how the association relationship evolved into aggregation and association relationships, and the drawing of the symbols, and the difference between class and object relationships. I watched many videos before and read a lot of articles, but each time I got more confusion as I watch/read, very frustrated. finally, I got it all figured out. To make your video more complete, it would be nice if you could add some real code along with the video. After all we want to code. Thank you.

On the last example at 9:09, there's a mistake on the relationship between the SubAcnt and the SavingAccount objects as the SubAcnt objects appear containing the SavingsAccount object, but it should be the other way around, with the filled diamond on the SavingsAccount side.
