Why it is important to perform an interface evaluation before the system is built?
The new system under development for Xtreme Vacation Cars has seven tables that will be implemented in a relational database. The expected average record size of these tables and the initial record count per table are given next.
| Table Name | Average Record Size | Initial Table Size (records) |
|
|
|
|
| New Car | 65 characters | 10,000 |
| Trade-in Car | 48 characters | 7,500 |
| Sales Invoice | 76 characters | 16,000 |
| Customer | 61 characters | 13,000 |
| Sales Person | 34 characters | 100 |
| Installed Option | 16 characters | 25,000 |
| Option | 28 characters | 500 |
Perform volumetrics analysis for the above system. Assume that the DBMS to 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. Expand the above table to show calculation results per year.
