Task 3 |20 points). Suppose that we have a ternary relationship R between entity sets A, B, and C such that (i) A has a key constraint and total participation; and (ii) C has a key constraint. These are the only constraints. A has attributes al and a2, with al being the key; B has attributes bl and b2, with bl being the key; and C has attributes Cl and C2, with CI being the key. R has no descriptive attributes. All of the above-mentioned attributes are to be stored as Strings of 10 characters. Write SQL statements that create tables corresponding to this information so as to capture as many of the constraints as possible. If you cannot capture some constraint, explain why
