Thank you soo much mam. You cleared all my doubts
Hi Ma'm , thank you for explaining so well. I have a question regarding knowing when something is a superkey . You have used a small dataset of which we can then look at it which combinations are possible for SK, but how can we identify or know which combinations SK and how may can be made when dealing with large datasets or something you have been given to create relationships?
How is the answer is 8 ma'am
Ma'am upload a video on Schema and 2 tier and 3 tier architecture and three schema architecture

she is a goat teacher
Sper keys ab, ac, ad
Super key da, dc, db
A is not candidate key and d is not candidate key
Marks, course, dept is true
All the explanation is ultimate and wonderful. But the pronunciation of "HERE" as "HARE" is weird. sorry to say this mam I apologize 🙏🙏
is the correct answer for the last question 12 super keys?
super keys---.ac,ab,ad,abc,abd,acd,abcd,a,d,db,dc,dcb ---> totally 12
You are super key to every student
