Thank you for this video and explanation of the mappings. It is by far the best for me to understand with code example. Quick and easy, not boring at all, right to the point.

[himanshubhusanrath]

Thank you so much for this video. The concepts are explained in a very detailed manner. This helped me a lot. May God bless you !

Regarding many-to-many, normally you would like to reuse the item rows when several customers share a same item. Thus the cascade type should not be ALL. Otherwise when you remove a customer, all its items will be removed as well, which makes sense in the case of one-to-many but not many-to-many (and many-to-one).

[antorodrigo]

Really useful to understand the entity annotations. Thanks!

[repakanagesh]

Great! thanks for covering all in single video

[gulbalasalamov]

Many thanks!
All type of relations worked for me

[Trazynn]

Don't worry man. Subscribed. Keep going. There's very little about entity mappings on Youtube.

[singarajusreedhar]

for aan example of bidirectional one t one when the get all is called on referencing entity it goes in infinte loop, not sure you face same issue

[atiqurrahman]

finally some decent explanation.
Thanks

[piumasan]

Great video! One question: why do you change from List to Set?

[pasupulaphaneesh]

Explanation is too fast. All the relationships are explained in one video in short time and couldn't able to understand. Appreciate if you can do one each relational mapping with example and showing DB changes along with the code.

[moggarajesh]

Nice explanation...and thank you so much

[manjunathmaruthi]

Hi, thanks for the video, would you mind explaining when to go with unidirectional, bidirectional & Join table

[achyutgawade]

Great explanation! But the video's sound is very poor, barely able to hear the voice on the laptop.

[SuperSenthil]

Seems like running fastly to cover the topics, if you do in slow way it will be easily understandable to all
