The four horsemen of data warehousing

I’ve been talking a lot to text mining vendors this week, as per a series of posts over on Text Technologies. Specifically, I’ve focused on the two with exhaustive extraction strategies, namely Attensity and Clarabridge. (Exhaustive extraction is Attensity’s term for separating the linguistic-analysis part of text mining from the DBMS-based BI/analytics part.)

So I asked each of Attensity and Clarabridge the side question as to which data warehouse software or appliances they were seeing. The answers were almost identical — Oracle, Microsoft SQL*Server, Teradata, and Netezza. One also mentioned MySQL and 2 HP prospects — but the HP sites were running NonStop SQL, not NeoView. Amazingly, there were no mentions of DB2. There also weren’t any mentions of the smaller specialist startups, such as DATAllegro, Greenplum, or Vertica.

    NonStop SQL *is* the NeoView database, running on the NonStop Kernel on standard HP hardware rather than fault-tolerant NonStop hardware.

    Jim,

    Are you asserting that ALL enhancements to the code to support analytics and data warehousing are rolled into upgrades to the main NonStop SQL product?

    No.

    My understanding is that the basis of NeoView is NonStop SQL/MX, which was a significant enhancement to NonStop SQL that targeted decision support, and became available on NonStop servers about five years ago. NonStop SQL uses HP’s NonStop Kernel OS, which has been adapted for standard HP servers. I believe that some of the NeoView enhancements are based on NonStop SQL and/or NonStop Kernel, and some of the NeoView enhancements run on other HP servers that surround the NonStop core.

    Jim,

    That makes sense. Thanks.

    Is there some way I can contact you directly? I have something I’d like to discuss privately. Please email me if that’s possible.

    Thanks, Jim

    Jim,

    One email address can be found in http://www.dbms2.com/2005/08/08/welcome-to-the-dbms2-blog-2/ and another at http://www.monash.com/contact.html

    Also, I emailed you directly from a third one.

    Best,

    CAM

    PS. Of course, I don’t know whether the email address I have for you is one you ordinarily care about …
