Data warehouses might just be the most critical resources to your becoming a customer-centric organization. They’re implemented on relational (or object/relational) database management systems that we call data warehouse databases. While there are only a few data warehouse database products from which to choose, and even though they’re familiar products from well-known suppliers, selecting a data warehouse database is a difficult task. This reports documents an evaluation framework for data warehouse databases that has been designed to help you select the product that is best for you. The framework has six major evaluation criteria: build and manage, access, performance and scalability, reliability and availability, analytics, and product marketing.
