What is the difference between a database and a data warehouse?

Aren\'t they the same thing, or at least written in the same thing (ie. Oracle RDBMS)?

Answer 1

A Data Warehousing (DW) is process for collecting and managing data from varied sources to provide meaningful business insights. A Data warehouse is typically used to connect and analyze business data from heterogeneous sources. The data warehouse is the core of the BI system which is built for data analysis and reporting.
