Question

How does the nature of source data impact data extraction techniques for a data warehouse?

a.

Source data is static, so historical data preservation is not required.

b.

Source data is structured uniformly, simplifying the extraction process.

c.

The temporal nature of source data necessitates capturing historical changes.

d.

Source data can be extracted easily without considering its attributes.

Answer: (c).The temporal nature of source data necessitates capturing historical changes. Explanation:The temporal nature of source data necessitates capturing historical changes, which impacts data extraction techniques.
