1. How is a formula related to what-if analysis?

2. You can also test the recommended indexes together with the indexes that you suggest with the "what-if analysis" before deployment.

3. At each level, the process of performing what-if analysis is repeated.

4. Any Changes in this section are temporary, for what-if analysis purposes, and discarded after logout.

5. The "what-if analysis" uses a virtual index under the covers to assess the effective of the indexes.

6. Finally, we develop a visual on-line query and analysis prototype to prove the feasibility of the proposed model and to show better support to what-if analysis.

7. Because it is so easy to experiment with different numbers, spreadsheet software is particularly useful for what-if analysis.
