Instead of checking further can we directly say , Every function dependency is divided into separate table and if key is not part of this then create 1 more table for key..?? Is it a correct?

[@pratikbal-x9e]

sir in example no 4, we found that AB ->C proves that R is not in 3NF, so we decomposed AB ->C i.e. R1(ABCI) but sir here A is a prime attribute and it finds I which is a non prime attribute so there should be no problem but sir you have again decomposed R1 to R11 and R12. Why so sir?

Hello, I have a question here. How do we deal with a case where there is a circular dependency that means in R(ABCD) we have given that A->B, B->C, C->D, D->A....how do we find the candidate key in that relation and then convert it further into normal forms?

Sir, Can you solve the following question to decompose the table into first 2NF and then 3NF? Given, the relation: R (a, b, c, d, e, f, g, h, i, j, k, f) and the FDs: a -> c, d, e; a, b, g, h -> i, j, k, f; j, i, g, h -> f, a, b. Decompose the given relation first into 2NF and then 3NF. It will be of great help if you help me in this sir.

I have a doubt.If relation is given A->DE and D is a prime attribute but E is not and A is not a superkey so can I say that this relation is valid for 3 normal form??

[@arunavasaha7051]

in 2nd and 3rd example why we are not creating a separate relation with only keys i.e. R(AB) when AB is a candidate key.. unlike 1st and previous examples?

[@aryanarya72]

Should be created

[@dhritimanroyghatak2408]

Consider a relation R(A,B,C,D,E) with set F= { A→CD, C→B,B→AE} What are the prime attributes of this Relation and Decompose the given relation in 3NF 🙏 sir solve this problem

[@asifiqbalkhan5601]

A,B,C are candidate keys and A,B,C are prime atributes this relation dont have any partial or transitive dependancy so, it is in 3NF

[@MuhammadJunaid-zv3kk]

*Sir in questions ma to apny simple ye btaya hua hai k A--->B OR AD--->E but sir actual problem hi to yahi ha hamin samjh ni ati k konsa attribute kis ko determine kr rha ha normal questions ma ye ni likha hota k ye attribute isko determine kr rha yahi chiz find krni parti ha so kindly koi method btayin jis sa hamin asani ho k ye attribute isko determine kr rha ye ni kr rha etc....

[@harshitharshit6448]

3rd example me BD and DE Me decompose kiya gya but B Part of cadidate key and prime attribute ek non prime ko identify karra to ye toh 2nf me hi nai hai kaise 3nf me ho gya

Sir if humne 3nf me decompose krne waqt ek relation me candidate key ko Bhi rakhte but sir if agar aisa relation mile jaha par ek hi letter ki ck ho tb kya uss suppose only 'A' toh waha pe relation kese bnega

[@parths.1903]

R22 Mei koi bhi candidate key ka attribute nahi hai sir ,,, then won't it be lossy ? ??

[@MohammedAli-qm2bg]

How do we decompose this relation? R(ABCD) F = {AB → C; BCD → A; D → A; B → C} The candidate key is BD.
