Consider the following collection of relations and dependencies. assume that each relation is obtained through decomposition from a relation with attributes abcdefghi and that all the known dependencies over relation abcdefghi are listed for each question. (the questions are independent of each other, obviously, since the given dependencies over abcdefghi are different.)for each (sub)relation: (a) state the strongest normal form that the relation is in. (b) if it is not in bcnf, decompose it into a collection of bcnf relations.1. r1(a, c, b, d, e), a b, c-d2. r2(a, b, f), ac-e, b-f3. r3(a, d), d g, g h4. r4(d, c, h, g), a , a5. r5(a, i, c, e)

Write a program that defines symbolic names for several string literals (chars between quotes). * use each symbolic name in a variable definition. * use of symbolic to compose the assembly code instruction set can perform vara = (vara - varb) + (varc - vard); ensure that variable is in unsigned integer data type. * you should also further enhance your symbolic logic block to to perform expression by introducing addition substitution rule. vara = (vara+varb) - (varc+vard). required: debug the disassembly code and note down the address and memory information.
