In the new system under development for Holiday Travel Vehicles, 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 for these tables and the initial record count per table are given next.
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 three years.
Perform a volumetric analysis for the Holiday Travel Vehicles system by calculating each value listed below: (1) calculate the value of "Total Record Size" of each table. (2) calculate the value of "Initial Table Volume" of each table.
(3) calculate the value of "Total Initial Volume". (4) calculate the value of "Total Volume in 3 years".
