The concepts and explanations at the beginning were really good; however, you didn't explain why did you use aggregation, or composition, or other relationships at the end. It was a bit confused when you previewed the design because the aggregation turned into composition.
Thanks for helping with my tough Software Engineering HW. Also, the music in this video is weird and happy, and suitable for a Nintendo game with Mario or Kirby.🎮😃
The first part was good, however; it would be better if you said all the stuff at the beginning while doing the diagram. It would’ve made it easier to understand. Especially since you added other elements that you didn’t explain before.
Am I the only one, or at the last example the author mixed up aggregation and composition. As composition supposed to be filled Dimond and aggregation empty. Correct me if I'm wrong.
It exhibits strange behavior because first he used composition, but when he clicked on the preview, it turned into aggregation. However, I think it is composition because the child object (Order Detail) would not be able to exist if the parent object (Order) disappears

Thank you for taking the time to watch our video and provide feedback. Regarding the arrows in the diagram, they typically indicate the direction of the relationship between the classes. We hope this explanation clears up any confusion you may have had. Please let us know if you have any further questions or concerns.
This doesn't go into details about relationships. It literally skims the most important bit about UMLs. Look! Arrow goes here, I hope you understand now. Explain your system, why you used that arrow there.
Thank you for the video. In composition, the child classes and parent classes can not exist independently ; this statement is wrong, i think. Parent class can exist upon a destruction. Only the child class cannot.
I don't know why this is trying to teach how to make class diagrams, i came here just to know how to use this tool, there are better and more intricate ways to learn

just wanna say to believe in Jesus for he loves u so much that he died and was raised from the dead so that u can have a relationship with him. Believe in him and ask GOD for forgiveness of your sins :) and turn away from them as well (repent)...ん
