Hey.... A+=ACE A+=ABE A+=ABC B+=B E+=E i think first we should take A terms after that we have E then E->A we have already A so we don't take but how did you taken A+=ABED how did you get D......? A+=ABCD here also how did you get D.......? please explain........
Write the algorithm to find the minimal cover for a sets of FD’s Consider R={A,B,C,D,E,F} .FD’s {A->C,AC->D,E->AD,E->H} Find the irreducible cover for this set of FD’s(minimal cover) Can u give me a solution sir.
UGH, I get so annoyed by these tutorials that start in English and then switch to Hindi. Seriously, why start talking in one language and then randomly switch to another? Is there a reason for that? Who is your intended audience for this tutorial?
I think we should follow the following steps
1. Singleton attributes on RHS
2. Eliminate extraneous attributes on LHS
3. Eliminate redundant F.D.s
correct
Came to clear confusion, now I'm more confused.
congrats
Me bhi😢
in the 2nd question ........................a+=ACE
a+=ABED
a+=ABCD
b+=B
e+=E
is it correct???plz recheck it n make me confirm???????????????
yes
Hey....
A+=ACE
A+=ABE
A+=ABC
B+=B
E+=E
i think first we should take A terms after that we have E then E->A we have already A so we don't take
but
how did you taken
A+=ABED
how did you get D......?
A+=ABCD
here also how did you get D.......?
please explain........
Yup
I think second question minimal cover is Fc = F also.
Wrong answer for 2 nd one
4:03
sir in last problem there is a --> b and b -->d so we can write this a-->d
that's why i'm suggesting to write like this because this will remove redundancy
you're right. you can either leave b->d as it is or replace it with a->d.Not both :)
Sir can please elaborate and explain bcoz I m a slow learner
plz help how to find extraneous attribute????????
what are you saying? in the first pbm you didnt done decomposing,in the next pbm you done decomposing*** it's so confusing
Write the algorithm to find the minimal cover for a sets of FD’s
Consider R={A,B,C,D,E,F} .FD’s {A->C,AC->D,E->AD,E->H} Find the irreducible
cover for this set of FD’s(minimal cover)
Can u give me a solution sir.
Thank you, sir.I can more clearly understand about minimal cover. This cideo is very helpfull for me.
thank very much ❤❤❤
Tysm
Thanks
All d relations are both left and right irreducible
Sir why you skip some steps in the middle please say clearly each and every step ........... Thank you
a=b keu nehi huya sir??
Why to get A from CD
sir do question ke diffrent method confusion hai
very nice video
i
Great video
Why do we use different methods in solving 2 diff examples?? Please tell....
in previous problem you didn't much concentrate on L.H.S term but in second problem why did you derived A from CD?
This is confusing
Please stick to one method of (A)+
Thank You
Either you should be speak in hindi or English...
Sir please use English language so we can understand
hindi hain hum watan hai hinduatan hamara
UGH, I get so annoyed by these tutorials that start in English and then switch to Hindi. Seriously, why start talking in one language and then randomly switch to another? Is there a reason for that? Who is your intended audience for this tutorial?
How A---E ?
because we r replacing cd with a.........so a->e
i think ques no.1 me D nae hoga
???????????????/
sir mininum 5 examples to krwaya kro
Consider a given relation R=(P,Q,R,S) with following set of
FDs: PQ→R
PS→Q
QS→P
PR→Q
S→R
Find the minimal set of FDs from the above set.
Please help
this is wrong
Totally wrong explaination
2nd one is completely wrong
Wrong totally
Wronggggg
a=b hoga
