warehouse?
A.Obtain data
B.Organize data
C.Cleanse data
D.Relate data
E.Disguise data

Answer 1

Data warehouses are designed to obtain, organize, cleanse, and relate data. Disguising data is not a function of a data warehouse as it implies altering or concealing data, not analyzing it.

Step-by-step explanation:

The function that is NOT one of the responsibilities of a data warehouse is E. Disguise data. Data warehouses are systems used for reporting and data analysis, and they are central repositories of integrated data from one or more disparate sources. Their key functions include to Obtain data from various sources, Organize data in a structured manner, Cleanse data to ensure quality and consistency, and Relate data to allow for meaningful analysis. Disguising data is not typically a function of a data warehouse as the term implies altering the appearance or concealing the nature of the data which would defeat the purpose of analyzing business intelligence.
