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)

Consider the following code snippet: #ifndef cashregister_h#define cashregister_hconst double max_balance = 6000000.0; class cashregister{public: cashregister(); cashregister(double new_balance); void set_balance(double new_balance); double get_balance() const; private: double balance[12]; }; double get_monthly_balance(cashregister bk, int month); #endifwhich of the following is correct? a)the header file is correct as given.b)the definition of max_balance should be removed since header files should not contain constants.c)the definition of cashregister should be removed since header files should not contain class definitions.d)the body of the get_monthly_balance function should be added to the header file.
