Taking an online class and it helped to hear this explained in different words. Thank you!
You explain better than my school teacher! Thank you!
I have a database exam tomorrow, your videos are really helpful, wish me luck!
Had you passed or failed in that?
@@pinkinandi7677 Passed, thanks! Now I'm a happy full time developer :)
@@Forestadash 😁😄
Please give examples on real life scenarios.
Thanks
No.
@@LaKillingFrenzyy LOL
short, concise and clear
One of the best explanations as always..
you are a hero techtud....thank you for this
Thank you , you explained this very well
confusion in fd nd pd, in the first example for fd, ABC→D, meant that D cant be determined by any of A B C, and then in second example, AC→P; Then A→P, how? As u told earlier tht A C cant be determined by P, according to first example of FD
A->D and D->P so in this case A->P ..... Here A is a subset of AC , So in this case it will be "pd"...
Shivam Srivastava # it means, D only determined if all three set ABC will present( thats why he said, A cant individual determine D, B cant individual determine D, C cant individual determine D) that is fully dependent, all three should be present.
In second example P is not fully dependent on AC, here P determined by A individually bcz there is transitive FD A->D, D->P so A->P
thank u brother .... i perfectly understood
Really helpful
Amazing 👌
That's why i love youtube Indian guys
Thank you so much!
I really understood clearly bro.........gud job....
Thanks a lot for this helpful vdo ❤️
Thank you bro.Keep upload more videos.
thank you you explain it very easily
Thank you for saving my final.
Helpful. Thanks man.
Thank you
Nicely explained!
Good JOB Bro
I am having troubles figuring out what kind of dependency this is
B exists only if A = special
B does not exist if A = nonspecial
thanks thank you sooo much.............
in 3 example A determines p which is the subset of AC then how is it a fully FD .explain plz?
P is NOT fully FD ... he said "NOT"...
nice lecture...........
plz post a video of Inclusion Dependencies and Template Dependencies...
nice explain
thanks!!
In trival FD A->A can't be trivial .
why?
Why
can anyone explain.... what is A+(A closure)?
u spoke opposite sentences for partially and fully dependent functional dependencies
great
Nice Lecture. (y)
pls make it understand properly about fully functional dependancy
did he said about partial fd
plz use comman example
good
Tqq sir
Not understanding Trivial FD, X subset of Y means it is Purely Relflexive property but you once again telling same as Tivial FD
Lifesaver
4:54 incorrect definition of subsets...the sign and whats you are saying are irrelevant
yes, he is using the symbol of subsets and calling it proper subset.
Partial FD explanation required
Thanks for not mixing English with Hindi
What is A closure?
Closure of A means the set of attributes determined by A.
Here, the attributes determined by A are A, D, P.
gajabbbbbbbbbbbbbbbbbbbbbbbb
+Madhavsingh Solanki ganduuuuuuuuuuuuuuu
anyone explain Trivial FD??????????
This guy has the nicest nails.
Please buy a better microphone!! Voice quality is terrible. Content is good though
sorry to say but you just made a very simple topic look much typical , try to make it easy to understand for a layman using real world scenario , bookish language is available every where
Don't understand
Okay boshda coooll
shave the hair on your fingers so that your video becomes more presentable..........just advising
explain properly by taking some real examples of relations
+Ankita Sharma why don't you do that instead of talking only . if someone has put a effort appreciate it !!!
+yash gupta That is called a feedback instead of just blabbering about the video. Get your social etiquettes first.
@KOUSTUBH UBHEGAONKER This not a feedback or request. It looks like an order. Please learn what all things come under social etiquettes then respond without being biased.
@Deepankar Singh The definition of feedback: " information about reactions to a product, a person's performance of a task, etc. which is used as a basis for improvement." Ankita's comment is a valid feedback idiot.
