Hatsoff to you sir! You are an amazing teacher. You reduce all these big scary topics to just basics which only need some practice before main exams like GATE, NET and these are always helpful in B.Tech and many other fields. I would like to help you in every aspect possible because I want you to really get paid off of the hard work you have done. I've been sharing all your videos with all my friends. I thank you from the bottom of my heart.

@aradhyasinghnaruka1345 5 лет назад

sir superb vidoes..hats off to you..i have only one small doubt.. at 11:27 min ..you said every one to one is many to one or one to many...how is that possible sir...in many to one we will have one entity from one set which have relation with 2 or more entities in other set..while one to one it can have relations at most one..then how is that statement valid..i didn't get this only in whole lecture

@casualsadi3144 5 лет назад

sorry in advance for my bad english.... in one to many u have one entity relating to 2 or more and in many to one u have 2or more entities relating to one ... so in every scenario ... one entity must relate to one entity... thus one to one exists in both of them....

@mkpkartik1359 4 года назад

1:1 is also 1:n how? Please explain still confused

@shimulbhattacharjee9560 4 года назад

I think because one entity can be related with maximum n entities. So, if it is 1:1 relationship then it can have 1:n relationship.

@vyrl4145 3 года назад

Sir your lecture is somehow missing something...like without explaining what is cardinality you started teaching cardinality mapping...you taught foreign key without explaining
