Comments on the analytic DBMS industry and Gartner’s Magic Quadrant for same

This year’s Gartner Magic Quadrant for Data Warehouse Database Management Systems is out.* I shall now comment, just as I did on the 2010, 2009, 2008, 2007, and 2006 Gartner Data Warehouse Database Management System Magic Quadrants, to varying extents. To frame the discussion, let me start by saying:

*As of February, 2012 — and surely for many months thereafter — Teradata is graciously paying for a link to the report.

Specific company comments, roughly in line with Gartner’s rough single-dimensional rank ordering, include: Read more

Terminology: Data mustering

I find myself in need of a word or phrase that means bring data together from various sources so that it’s ready to be used, where the use can be analysis or operations. The first words I thought of were “aggregation” and “collection,” but they both have other meanings in IT. Even “data marshalling” has a specific meaning different from what I want. So instead, I’ll go with data mustering.

I mean for the term “data mustering” to encompass at least three scenarios:

Let me explain what I mean by each.  Read more

Exasol update

I last wrote about Exasol in 2008. After talking with the team Friday, I’m fixing that now. :) The general theme was as you’d expect: Since last we talked, Exasol has added some new management, put some effort into sales and marketing, got some customers, kept enhancing the product and so on.

Top-level points included:

Very brief CEP/streaming catchup

When I agreed to launch the StreamBase LiveView product via DBMS 2, I planned to catch up on the whole CEP/streaming area first. Due to the power and internet outages last week, that didn’t entirely happen. So I’ll do a bit of that now, albeit more cryptically than I hoped and intended.

Meanwhile, if you want to see technically nitty-gritty posts about the CEP/streaming area, you may want to look at my CEP/streaming coverage circa 2007-9, based on conversations with (among others) Mike Stonebraker, John Bates, and Mark Tsimelzon.

Compression in Sybase ASE 15.7

Sybase recently came up with Adaptive Server Enterprise 15.7, which is essentially the “Make SAP happy” release. Features that were slated for 2012 release, but which SAP wanted, were accelerated into 2011. Features that weren’t slated for 2012, but which SAP wanted, were also brought into 2011. Not coincidentally, SAP Business Suite will soon run on Sybase Adaptive Server Enterprise 15.7.

15.7 turns out to be the first release of Sybase ASE with data compression. Sybase fondly believes that it is matching DB2 and leapfrogging Oracle in compression rate with a single compression scheme, namely page-level tokenization. More precisely, SAP and Sybase seem to believe that about compression rates for actual SAP application databases, based on some degree of testing.   Read more

Virtual data marts in Sybase IQ

I made a few remarks about Sybase IQ 15.3 when it became generally available in July. Now that I’ve had a current briefing, I’ll make a few more.

The key enhancement in Sybase IQ 15.3 is distributed query — what others might call parallel query — aka PlexQ. A Sybase IQ query can now be distributed among many nodes, all talking to the same SAN (Storage-Area Network). Any Sybase IQ node can take the responsibility of being the “leader” for that particular query.

In itself, this isn’t that impressive; all the same things could have been said about pre-Exadata Oracle.* But PlexQ goes somewhat further than just removing a bottleneck from Sybase IQ. Notably, Sybase has rolled out a virtual data mart capability. Highlights of the Sybase IQ virtual data mart story include:   Read more

Sybase IQ soundbites

Sybase made a total hash of the timing of this week’s press release. I got annoyed after they promised to inform me of the new embargo time, then broke the promise. Other people got annoyed earlier than that.

So be it. Below is the draft of a post I was holding, with brackets added around one word that is no longer accurate.

I don’t write enough about Sybase IQ. That said, I offered a couple of quotes to a reporter [yesterday] in connection with the general availability of Sybase IQ 15.3. Lightly edited, they go:

Beyond that, I should note:

Eight kinds of analytic database (Part 1)

Analytic data management technology has blossomed, leading to many questions along the lines of “So which products should I use for which category of problem?” The old EDW/data mart dichotomy is hopelessly outdated for that purpose, and adding a third category for “big data” is little help.

Let’s try eight categories instead. While no categorization is ever perfect, these each have at least some degree of technical homogeneity. Figuring out which types of analytic database you have or need — and in most cases you’ll need several — is a great early step in your analytic technology planning.  Read more

Temporal data, time series, and imprecise predicates

I’ve been confused about temporal data management for a while, because there are several different things going on.

In essence, the point of time series/event series SQL functionality is to do SQL against incomplete, imprecise, or derived data.* Read more
