A conceptual schema is systematically mapped to a relational schema, resulting in exactly 8 distinct relational tables. Based on the numerical rules governing key counts per table in the relational model, let P be the exact total number of Primary Keys across the entire schema. Let C be the absolute minimum total number of Candidate Keys across the schema. Let A be the absolute minimum total number of Alternate Keys across the schema. Calculate the value of (P × 3) + C - A.
