The text lists the following (the student should pick at least three of these):
i. The process of developing a data warehouse forces an organization to better understand the data
that it is currently collecting and, equally important, what data is not being collected.
ii. A data warehouse provides a centralized view of all data being collected across the enterprise and
provides a means of determining data that is inconsistent.
iii. Once all data is identified as consistent, an organization can generate one version of the truth. This is
important when the company wants to report consistent statistics about itself, such as revenue or
number of employees.
iv. By having a data warehouse, snapshots of data can be taken over time. This creates a historical
record of data, which allows for an analysis of trends.
v. A data warehouse provides tools to combine data, which can provide new information and analysis.
