Assume these are the values that exist for all time (e.g., the toys shown always cost the amount shown) and that boys with the same name are the same person. If necessary, decompose the initial relation into a set of non-loss 3NF relations by showing the relations, attributes, and tuples. Show complete relations with attribute headings and all data values in the tuples of your relations. Determine the number of 3NF relations you end up with after normalization, write this number, and then circle the number.
