In the past, a data warehouse was used primarily in back-office business processes. By contrast, the active data warehouse (ADW) is an operational system used during interactions with customers, suppliers, employees and business partners. As a result, requirements for higher levels of availability are emerging for the ADW.

A data warehouse built with Teradata Servers and the Teradata Database offers levels of data availability expected in a world-class operational system. An ADW with fallback enabled provides recovery from pathological failure scenarios, such as the complete failure of RAID devices, disconnection of I/O cables and various software errors.
