In the new system under development for Benny's Used Cars, seven tables will be implemented in the new relational database. These tables are New Vehicle, Trade-in Vehicle, Sales Invoice, Customer, Salesperson, Installed Option, and Option. The expected average record size in characters for these tables and the initial record count per table are given next.
| New Vehicle | 55 | 10,000 | 
| Trade-in Vehicle | 38 | 7,500 | 
| Sales Invoice | 66 | 16,000 | 
| Customer | 51 | 13,000 | 
| Salesperson | 24 | 100 | 
| Installed Option | 6 | 25,000 | 
| Option | 18 | 500 | 
Perform a volumetrics analysis for the system. Assume that the DBMS
that will be used to implement the system requires 35% overhead to
be factored into the estimates. Also, assume a growth rate for the
company of 10% per year. The systems development team wants to
ensure that adequate hardware is obtained for the next 3 years.
