Data Warehouse

Explanation:

A “data warehouse” is a repository of current and historical data of potential interest to managers throughout the organisation, that has been organized by subject to assist decision makers to be guided in their decision making.

The data in the data warehouse may be recent or ancient, and may be in its raw form or may have been processed and/or summarized.

Absence of data warehouse in an organisation displays the reality that decision making may not be at its best and that the quality of decisions can be improved, no matter how good they maybe without a data warehouse.
