Sir,but you didn't specified the difference between specialization and generalization.what actually happens is generalisation here what about the other thing?
Hello Sir, in the given example the primary key is "pname" and we are using same PK in other 3 tables, so are they work as PK in other 3 tables or we need a separate PK for those tables?

Sir,but you didn't specified the difference between specialization and generalization.what actually happens is generalisation here what about the other thing?
generalization is nothing but unioun of two or more lower level into to form higher level entity
specialization is reverse of generalization
It is all blowing out of brain

Really! Superb Sir! You're Great!
Explain is very well sir
Thank you so much for the explanation
Sir again you are a genius
Clearly Explained.. thank you
is this good approach to make separate table for each? Every table has repeated column. how we can reduce repeatation of colums
You can use only primary key of parent entity while making table of child entities
well explained, Can you please sir explain me what is Qualification concept in Database ? Thanks Professor.
