High-End Data Warehouses - "Shared Nothing" RDBMSs

Published: 16 October 2000

ID: G0092804

Analyst(s): Norma Schroder

Summary

In this Perspective, Gartner Dataquest discusses the market for RDBMSs targeting high-end data-warehousing, that is, those with "shared nothing" parallel architectures. There are only three such offerings --NCR Teradata, IBM DB2 EEE on SP2, and Informix XPS. The license revenue for RDBMS software in this specialized segment is less than 1 percent of the license revenue in the broader market of DBMSs for decision support. The terabytes of data generated by e-commerce will increase the demand for "shared nothing" architecture RDBMSs for the data warehouse.
