Sir you are terrific... You are best teacher in youtube i have come across...sir you are doing great job...your style of explaining and making things simple and easier is commendable. Usually i dont put comments in youtube but i couldnt resist in your case. Sir where are you from and where do you teach?
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?
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?
Thank you so much dear Jatin, keep learning & supporting, stay tuned ! You can also visit our website www.knowledgegate.in for more amazing contents & courses !
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?

Thank-you sir for amazing video !!! Sir Ek Doubt Tha ki Question me Jitni bhi Dependecies di hai hum usika hi Table Create Kar dete hai to uske Bad Ye sab step karne ki to Zaroorat hi nahi hai. To ham ye step kyu kar rahe hai?
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.
*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....

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
Can't resist giving feedback after watching his videos on FD(Part 3.1) till 3NF(Part 4.8). - His videos are okay to understand the concepts intuitively but will be of little help if you solely rely on it for GATE. Reading a standard book or watching lectures of some reputed colleges (as available on NPTEL/Stanford/MIT) is a must to get the technical jargon and to get the concepts right. - Mr. Sanchit Jain deliberately took examples involving a single candidate key, while solving problems on 3NF, and pretended that this is all that will be asked in GATE/NET. This will give the candidates a sense of "complete" understanding when, in fact, they just learned and practiced the skills to solve a subset of the possible questions. This series was recommended to me by an accomplice, but I won't recommend it if you want to appear for GATE. Supplementing these videos with a reference text might prove helpful. **Views are personal**

Sir in question no 4 . There is mistake because sir here in R1 we decompose it but sir why because here candidate key is A ,so already the table is in 3 NF so why we decompose it into R11 and R12
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??
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

yep
I have an exam in an hour xD
YYY
excellent video with really good examples and explanation. love it sir
If there is more than one candidate key than how to normalize 2 and 3 normal form. Plz Plz upload one lecture also.
I will watch the whole advt . Thats the only tribute i can pay to him.
very nice explanation..............Sir plz start uploading videos on COA..
Best explanation sir, it will helps me a lot in fourtcoming exam .Thank you sir
Great videos!
Just reduce the number of ads, or organize them in a little better way as it breaks the concentration while watching.

Great teacher❤❤
Thank you so much friend.. keep following and watching videos..
Sir please make a vedio in which we have more than one candidate key
Thanku sir..we love you knowledge gate
sir can you please teach how to check dependency preserving and lossy/lossless nature of decomposition
You r the best teacher
Thanku so much sir
Thanks 🙏 Sir
Great Explaination sir,God Bless you sir

Awesome explanation sir.
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.

Very good explanation sir tq sir
Very precise lecture
Thanks sir 😆
SIR VERY GOOD LECTURE SIR
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
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
Best explanation ever!
Nice explnaition

i agree....but it gives a basic understanding for the beginners so that it becomes quite easy to learn further....
Thanks sir but also upload computer network series please thanks again
You might find confusing at first, but believe me you won't find simpler explanation than this!!
Kya ye method se semester exam me solve kr skte h????....jldi bta dijye...mera exam 30 may ko h

Great sir 👍
you are god. thank you for such wonderful explanation
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?
Should be created
Sir in question no 4 . There is mistake because sir here in R1 we decompose it but sir why because here candidate key is A ,so already the table is in 3 NF so why we decompose it into R11 and R12
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??
Sir, plzz plzz make videos on 4th normal form also
In 1st Example, R12 mei, B candidate key kaise Bana? Can you please clear my doubt , tomorrow I'm having my exam... thanks sir
sir pls upload videos on lossless join and dependency preserving
Sir, can you kindly explain again why have you made the table R4(A,B,D) in decomposition ? I have a doubt in this part .
Same because H determines J but it's not a part of Candidate key.
Kindly explain anyone
thank you so much sir.
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 can we combine the tables R11 and R4 in last 4th example ? 20:39
21:11 just to convert a relationship table to 3NF we need 6 table so will it take more space in database?? Increase the complexity??
This is priceless!
How do we decompose this relation? R(ABCD) F = {AB → C; BCD → A; D → A; B → C} The candidate key is BD.
GREAT

@KNOWLEDGE GATE Sir Beta kabhi bhi prime atribute kaise hoga kyonkin wo khud alpha se nikala jaa skta h ye baat mujhe smjh nhi ayi kya aap please alaborate karenge.Thank you
