Common and consistent information brings coherence to the way an enterprise is managed. Users can quickly access accurate, real-time information, and collaborate effectively using shared information across departments and divisions. System-wide changes can be made instantly from one location and it’s easy to implement a higher level of security around usage and information flow. A data warehouse can store huge amounts of historical data, enabling advanced business intelligence analysis of different time periods and trends, which allow future predictions. A transactional database is not normally able to store this amount of data, and a transactional system cannot usually generate trend reports.

The Teradata product is referred to as a "data warehouse system" and stores and manages data. The data warehouses use a "shared nothing" architecture which means that each server node has its own memory and processing power.
