Why might an e$-$commerce company wish to have a data warehouse?

a$.$

With a data warehouse, the company can almost certainly get a better rate on its data storage per square$-$foot.

b$.$

A data warehouse can accommodate more employees to work as data analysts than most other office space configurations can account for.

c$.$

Once it has established a data warehouse, the company will not need to comply with General Data Protection Regulation $($GDPR$).$

d$.$

Because data that the company obtains might exist in any of several different formats, the company wants to have a single $$go$-$to$$ location in which data is kept and can easily be retrieved.
