For several years now, the approaches to data warehousing have been dominated by Bill Inmon and Ralph Kimball. Bill Inmon has espoused the data warehouse concept while Ralph Kimball advocates data marts as the basis for a DSS architecture. This has sparked tremendous divergence in how each corporation decides to implement their DSS architecture. We at DM Review would like to issue a challenge to both Bill and Ralph to debate their views in a public forum in 1999. Several readers have told me that Ralph has already issued this challenge during his seminars, and Bill Inmon is more than willing to accept the challenge. This should be one of the most exciting debates and of great interest to the entire industry. Stay tuned for more particulars on this "Great Debate" in the next few issues.
