In your own words what is a data warehouse and why is it important to have another copy of the data in a data warehouse?
A data warehouse is a database platform that stores historical data for an organization specifically for the purpose of analytically looking at said data such as looking at trends over a period of time. It is important to have another copy of the data in a data warehouse in order to improve query time because data warehouses may be laid out differently than the main operational database due to attributes such as query time being prioritized.
