Which of the following statements are true about data aggregation?
Correct Answer:
B is incorrect. Data aggregation can be user-based. Personal data aggregation services offer the user a single point for collection of their personal information from other Web sites.

Performing this type of data aggregation is sometimes referred to as "screen scraping."
