This and that

I have various subjects backed up that I don’t really want to write about at traditional blog-post length.  Here are a few of them.

Vertica offers a post on its 3.5 release, with a riff on the popular theme “We’ve fixed some weaknesses in our prior versions that we didn’t previously say we had.” More important, Vertica is pretty clear on the virtues of its hybrid columnar architecture.

Speaking of which — Oracle is going true hybrid columnar as well. I don’t have details or timing, however.

Dave Kellogg of Mark Logic wrote in to amusedly point out  Oracle’s anti-MarkLogic collateral. The very first charge Oracle levies is that MarkLogic goes beyond the emerging XQuery standard to add additional functionality. Considering Oracle’s approach to SQL standards, I tend to share Dave’s amusement.

Bill Conniff of Xponent LLC wrote in to tell of a vastly cheaper and less functional approach to XML management, apparently geared to looking at very large XML files one at a time.

Cayuga is a Cornell research project in complex event processing (CEP). There’s a Cayuga academic home page, a Sourceforge page for some open source Cayuga CEP code, and so on. Minsheng Hong, writing from a Vertica email address, tipped me off some months ago. The basic idea seems to be to do lots of queries very quickly, rather than a smaller number of queries over and over again. Whether this is an advance in anything but open-sourceness over Apama or Aleri I couldn’t say, but I do think it’s a different focus than that of StreamBase or pre-Aleri Coral8.

And finally, editor Doug Henschen listed his 15 favorite Intelligent Enterprise blog posts of 2009 — four each by Seth Grimes and Doug himself, three by Cindi Howson, two by me,* and one each by Mark Smith and Neil Raden.

*Doug selects up to three posts a month from here to republish.

    Curt,

    Those weren’t MY favorites! Those were Intelligent Enterprise reader favorites based on page-view counts. As one of the newest contributors to Intelligent Enterprise, your blog hasn’t had as much time as some others to build up a following. And then there’s the fact that we syndicate your stuff Utne Readers style, so plenty of people read it here (at DBMS2) first!

    Happy New Year to all!
    Doug Henschen, Intelligent Enterprise
