Thomas C. Redman
Perhaps no subject is more important, or bedeviling, to those who labor to leverage their data warehouses than data quality. When populated with high-quality, trusted data, warehouses including the associated decision support, business intelligence (BI) and data mining tools are powerful enablers. They can help businesses see customers and markets in new ways, create new products and services, and improve operations. In so doing, these organizations distance themselves from competitors.
