3. (2pts) Consider the fact table with four dimensions: Date(D), Product(P), Store(S), and Customer(C) and one measure Sale value. Assume the domain size for each dimension is |D=365, [P] = 2000, IST=200, [C]= 50000. There are 10 million sale records in the fact table. How may bytes do we need to store the whole bitmap index (simplest form) for Product dimension? (1 bytes = 8 bits) 3.
