Given R = (A, B, C, D, E, G, H, I) and the set F of functional dependencies: BDEI → GH EG → AI DH → CE I → BD use the BCNF algorithm to generate a database design. Is your design dependency-preserving? Why or why not?

Date: Problem 1 A wire of un-stretched length to and diameter D is used to suspend a block of weight w. The wire, of unknown composition, has a Young's modulus of Y. la.) Assuming the wire obeys Hooke's law, what is the force constant k of the wire? 1b) What would the weight w have to be to stretch the wire by a given Δ Given values...
Given relation R(A, B, C, D, E, F), give (i) the key(s) of R and (ii) the normal form of R if the FDs are: (d) AB -> C, CD -> EF (e) AB -> CD, D -> EF, C -> AB. (f) ABC -> D, ABC -> E, ABC -> F.
Q3: Given a relational schema R = {A,B,C,D,E,F,G,H,1,J,K} and a set of functional dependencies F {A B C D E, E F G H I J,AI →K} and a key(R) = AI = 1. Is R in BCNF? If yes, justify your answer [5 points] 2. If no, explain why and decompose R for two levels only [10 points] 3. Check whether the decomposition in step 2 dependency preserved or not [5 points]
