F
Three-tier architectures generally result in higher long-term costs.
F
Cloud computing will have a limited impact on three-tier applications.
F
Advances in computer hardware, particularly the emergence of affordable mass storage and parallel computer architectures, was one of the key advances that led to the emergence of data warehousing.
T
The development of the relational data model did not contribute to the emergence of data warehousing.
F
The need for data warehousing in an organization is driven by its need for an integrated view of high-quality data.

F
Informational systems are designed to support decision making based on historical point-in-time and prediction data.

T
An independent data mart is filled with data extracted from the operational environment without the benefit of a data warehouse.
T
A data mart is a data warehouse that contains data that can be used across the entire organization.
