Data quality is often defined as the suitability of data for its intended purpose. Strategic business initiatives such as Customer Relationship Management (CRM), supply chain management, and business intelligence can be thwarted by poor data quality. In fact, the Data Warehousing Institute estimates that data quality problems cost U.S. businesses more than $600 billion a year.

Teradata Warehouse Miner is unique analytic software that allows users to perform data quality functions entirely within a Teradata Database. Representing a dramatic shift from past non-warehouse-resident architectures, Teradata Warehouse Miner users perform data quality functions without additional hardware, software, and associated data management processes.
