UML Class Diagrams - Association and Multiplicity

[@siddharthshinde4480]

The 'life cycle' of a part object is so important key to explain the difference between aggregation and composition. A lot of tutorials just don't mention this. Thanks for making this tutorial.

[@avimehenwal]

That example sums up everything I had been trying to understand since last 2 years XD Super thanks for the video.

[@franklin8184]

Simple, clear, and direct...2 semesters of confusion cleared in

[@ML-ie4xc]

Learned more in 9 minutes than from reading 90 pages of my boring UML textbook. Thank you.

[@majed1490]

same here

[@martinhurrell7380]

Short, to the point, accurate and clear - one of the best short tutorials that I've seen. Thank you

[@lucasgroves137]

[@maryr94]

[@wennwenn1422]

[@Anecxina]

Simple and easy explained! Thank you!

[@ej_entertain]

One semester illustrated nicely in 10 minutes. That was greatly explained. Thank you.

[@danish6192]

Unary Associations and Attributes are the same thing. And I hit Like! Really so many times I've seen people saying similar things without telling the exact difference or mentioning that they are same thing with different approaches. Thanks for Saying it straight forward, it isn't hard to say something that it is.

[@SpicyLifeee]

Really very easy explanation with real life examples! It would be great if you organise playlists. thank-you so much!

[@riyajpatel1841]

Your way of teaching is simply awesome..

[@kpwwm8104]

finally a very crystal clear video.

[@pradeep6295]

Awesome video tutorial ! you have some unique talent, I generally dont add comments but this video was just too good, Simple videos are so difficult to make !

[@KeyesAnthony]

This was great. I didn't know that a unary association == the attribute(s) of a class. That cleared up a lot of confusion for me. Thank you

[@sammclaren6965]

Such a great explanation. We need more teachers like you. Thank you very much.

[@enzoys]

You are the best teacher available. Can you please provide new videos on Mockito?

[@eg2821]

this 9 minute video is way better than my teacher explaining the same thing for 2 hours.

[@utilizator1701]

Not exactly the level of difficulty I have wanted, but it is good that are videos where are presented more difficult concepts about class diagrams.

[@informativecontent4778]

Thank you a lot, Miss!

[@srsqtee]

In the house example, is it wrong to say that Mortgage is a composition with House? Can mortgage exist without a house? Or is it that we don't put composition when working with multiplicity?

[@yasserkhreis9605]

Very Well-ExplainedThank you

[@spidernerds]

its very helpful videos god bless you

[@fk8607]

great explanation 👏

[@vickyog5995]

Very useful and helpful thank you! But could the Mortgage class also be composite to the House Class because without the House Class there would never be a mortgage ?

[@rxseqvartz5679]

Mortgage isn't part of the house so it cant be a whole part relationship (aggregation or composition). This is how I understood it.

[@alishshrsetha1290]

Such a good explanation. Thanks for sharing :D

[@subhampanara]

can you explain me too ???

[@shathaalnahdi4823]

Very helpful ,thank you.

wow amazing explanation

[@xxshaw1822]

Best Explanation

[@fatemazohra4792]

amazingly explained!

[@ayanchoudhury4060]

Hi Margret, regarding the last example, can you explain why there exists a Binary relationship between House and Mortgage? Shouldn't that be a directed line pointing from House to Mortgage?

[@margretposch4827]

The idea here is that the house knows about the mortgage, and the mortgage knows about the house. (A mortgage document includes not only information about the mortgage rate, etc. but also the address of the house.)

[@ayanchoudhury4060]

@@margretposch4827 Thanks for the clarification. Great vid!

[@billyjordan2653]

8:44 EXCELLENT DIAGRAM!

[@VigneshPai]

Why are there no arrows in the last diagram to denote 'has a' Association ?

[@manjitshakya6457]

Finally understood multiplicity

[@hamuraku]

thanks for explanation, this makes sense
