Question

Quizplus · Accepted Answer

A data warehouse is a subject-oriented (focused on specific areas of interest), integrated (combines data from multiple sources), time-variant (includes historical data), nonvolatile (data is not frequently updated or deleted) collection of data used for analytics and decision making. Data marts are similar but are smaller subsets of a data warehouse, focused on a specific department or area of interest. A data center refers to the physical location where data is stored and managed, and an information desk is a resource for providing information to individuals or customers.
