We’ve developed a framework to help you select the data warehouse database product that is best for you, minimizing the time and risk of your selection process. The framework has four major evaluation criteria: Architecture, build and manage functionality, analytics, and product and company viability. Each of these major criteria has multiple sub-criteria. This report presents a matrix of our evaluations of four data warehouse database products against that framework: IBM DB2 Data Warehouse Enterprise Edition Version 8.1, Oracle9i Enterprise Edition, Sybase IQ 12.5, and Teradata Warehouse 7.0.
