Gee Dennis, you make it sound glamorous. Will your next career be one as a spin doctor? :)

[EMAIL PROTECTED] -----Original Message----- Sent: Friday, November 08, 2002 4:49 PM To: Multiple recipients of list ORACLE-L Dennis, Well, as a matter of fact, I do prefer Kimball to Inmon. I was unaware of their disagreement on ODS, which makes sense I guess, since I've read little of Inmon. My thoughts on ODS were based on discussions with former colleagues. We did have something at BlueCross that we expended a lot of energy in designing, though we didn't call it an ODS.

He coined the term Operational Data Store. I do not purport to be a data warehouse expert at the least, but several years ago I studied the literature quite a bit and tried to keep on top of the topics. And the subject has evolved some since then. At that time, there tended to be two separate camps, followers of Ralph Kimball's ideas and followers of Bill Inmon's ideas. Well, truthfully there was a third group, the rabid Fifth Normal Form advocates that insisted on fully normalizing their DW model. The issue that split the Inmon and Kimball camps was the ODS. The two titans of the industry even had some head-to-head debates at large conferences. Ralph always claimed that the ODS was no big deal, you probably had a loading area somewhere and if you had to give it a name, fine call it an ODS. Bill insisted very strongly that the ODS was THE crucial concept in data warehousing and if you didn't design that part correctly your data warehouse was sure to fail. Since I could easily read and understand Ralph's articles and I could never figure out what Bill was saying, I tended to follow Ralph's advice. Given your statements, Jared you sound like a classic Kimball follower as well. But the world moves on, and since the hot topic has been "real-time data warehouses", so I assume the ODS controversy is now moot. Today Inmon's big topic is the "Corporate Information Factory".

It isn't that issue at all. No two people can agree on what an ODS is at all, much less compare it to a DW. To me for instance, an ODS is a place to stage data for the final stages of some other process, be it a DW, or anything else. An ODS is a rather generic term, and therefor whatever you want it to be.
