Create an empty relational table to store information about the names of employers and the total number of positions offered by each employer. A name of relational table and the names of columns are up to you. Enforce the appropriate primary key and referential integrity constraints (if any). Next, load into the table information about the names of employers together with the total number of positions offered by each employer. If an employer offers no position then its name must be recorded with a number zero (0).
