    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

    • @satishkumar-wf7ml
      @satishkumar-wf7ml Před 7 lety +4

      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"...

    • @hemanegikhatri6075
      @hemanegikhatri6075 Před 7 lety +3

      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

    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

    Not understanding Trivial FD, X subset of Y means it is Purely Relflexive property but you once again telling same as Tivial FD

      @dishendra. Před 4 lety +1

      yes, he is using the symbol of subsets and calling it proper subset.

    • @harikrishnanr4808
      @harikrishnanr4808 Před 7 lety

      Closure of A means the set of attributes determined by A.
      Here, the attributes determined by A are A, D, P.

      +yash gupta That is called a feedback instead of just blabbering about the video. Get your social etiquettes first.

    • @deepankarsingh7230
      @deepankarsingh7230 Před 8 lety +3

      @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.

    • @VONisHope
      @VONisHope Před 6 lety

      @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.
