Information on Data Warehouses

Database management system (DBMS) or a data mart is a small data warehouse, designed for the end-user needs in a strategic business unit (SBU) or a department. Data warehouse are used to house different information that can be grouped together to give clarification. Data warehouses are Historical, Consistent Non-volatile, and Multi-dimensional. They provide IS with structured data and protectional housing for information that can be accessed and viewed safely by users and a data management team. With that being said without Data Warehouses, IS would lack security.
