Answer to Question 1

Advertising, subscriptions, selling collected marketing information, and directing buyers to sellers could all generate revenue. Student evaluations will vary. A sample answer is: I would think the most successful method would be through collecting marketing information, because as a portal that links to large amounts of external information and attracts repeat customers, the portal would have the opportunity to gather a lot of information about each user.

Answer to Question 2

A data warehouse stores current and historical data of potential interest throughout a company. Data warehouses gather data from multiple operational systems inside the organization. Data warehouses make data available, but do not allow that information to be altered. Data marts are subsets of data warehouses, in which a highly focused portion of an organization's data is placed in a separate database for specific users. Data marts are decentralized, whereas data warehouses are enterprise-wide, central locations for data.
