1. Suppose that the small firm for which you designed the Netflix®-like DVD rental database has established an Internet presence and their sales are growing rapidly. You have been asked to examine the database to make sure that it can grow to support at least a million transactions per day. Your assignment is to examine the Oracle or MSSQL version of the Netflix schema provided that you have now reverse engineered into Visio or a database design tool of your choice, and identify performance and other scaling problems. The frequently occurring operational transactions are:

· A customer updating their wish list on the web.

· The receipt of a DVD, with the corresponding mailing of the next in-stock DVD from the customer's wish list.

· Monthly billing of each customer's credit card.

Within no more than two paragraphs discuss the following topics:

· What changes would you make to the provided schema so that it can scale to handle a million or more transactions per day?

· What indexes would you add?

· Would you denormalize? If you would denormalize, how would you maintain the denormalizations?
