Data exploration vs. data visualization
I’ve tended to conflate data exploration and data visualization, and I’m far from alone in doing so. But a recent Economist article is a useful reminder that they aren’t exactly the same thing. Read more

Another reason to expect number-crunching and big-data management to converge

February 2010 data warehouse DBMS news roundup
February is usually a busy month for data warehouse DBMS product releases, product announcements, and other real or contrived data warehouse DBMS news, and it can get pretty confusing trying to keep those categories of “news” apart.* This year is no exception, although several vendors – including Teradata and Netezza – are taking “rolling thunder” approaches, doing some of their announcements this month while holding others back for March or April.
*I probably have it worse than most people in that regard, because my clients run tentative feature lists and announcement schedules by me well in advance, which may get changed multiple times before the final dates roll around. I also occasionally miss some detail, if it wasn’t in a pre-briefing but gets added at the end.
Anyhow, the three big themes of this month’s announcements are probably:
- Integrating different kinds of analytic processing into databases and DBMS.
- Taking advantage of hardware advances.
- Playing catchup in areas where small vendors’ products weren’t mature yet.

TwinFin(i) – Netezza’s version of a parallel analytic platform
Much like Aster Data did in Aster 4.0 and now Aster 4.5, Netezza is announcing a general parallel big data analytic platform strategy. It is called Netezza TwinFin(i), it is a chargeable option for the Netezza TwinFin appliance, and many announced details are on the vague side, with Netezza promising more clarity at or before its Enzee Universe conference in June. At a high level, the Aster and Netezza approaches compare/contrast as follows: Read more

Aster Data nCluster 4.5
Like Vertica, Netezza, and Teradata, Aster is using this week to pre-announce a forthcoming product release, Aster Data nCluster 4.5. Aster is really hanging its identity on “Big Data Analytics” or some variant of that concept, and so the two major named parts of Aster nCluster 4.5 are:
- Aster Data Analytic Foundation, a set of analytic packages prebuilt in Aster’s SQL-MapReduce
- Aster Data Developer Express, an Eclipse-based IDE (Integrated Development Environment) for developing and testing applications built on Aster nCluster, Aster SQL-MapReduce, and Aster Data Analytic Foundation
And in other Aster news:
- Along with the development GUI in Aster nCluster 4.5, there is also a new administrative GUI.
- Aster has certified that nCluster works with Fusion I/O boards, because at least one retail industry prospect cares. However, that in no way means that arm’s-length Fusion I/O certification is Aster’s ultimate solid-state memory strategy.
- I had the wrong impression about how far Aster/SAS integration has gotten. So far, it’s just at the connector level.
Aster Data Developer Express evidently does some cool stuff, like providing some sort of parallelism testing right on your desktop. It also generates lots of stub code, saving humans from the tedium of doing that. Useful, obviously.
But mainly, I want to write about the analytic packages. Read more

Vertica 4.0
Vertica briefed me last month on its forthcoming Vertica 4.0 release. I think it’s fair to say that Vertica 4.0 is mainly a cleanup/catchup release, washing away some of the tradeoffs Vertica had previously made in support of its innovative DBMS architecture.
For starters, there’s a lot of new analytic functionality. This isn’t Aster/Netezza-style ambitious. Rather, there’s a lot more SQL-99 functionality, plus some time series extensions of the sort that financial services firms – an important market for Vertica – need and love. Vertica did suggest a couple of these time series extensions are innovative, but I haven’t yet gotten detail about those.
Perhaps even more important, Vertica is cleaning up a lot of its previous SQL optimization and execution weirdnesses. In no particular order, I was told: Read more

Intelligent Enterprise’s Editors’/Editor’s Choice list for 2010
As he has before, Intelligent Enterprise Editor Doug Henschen
- Personally selected annual lists of 12 “Most influential” companies and 36 “Companies to watch” in analytics- and database-related sectors.
- Made it clear that these are his personal selections.
- Nonetheless has called it an Editors’ Choice list, rather than Editor’s Choice.
(Actually, he’s really called it an “award.”)
Comments on the Gartner 2009/2010 Data Warehouse Database Management System Magic Quadrant
At intervals of little over a year, Gartner Group publishes a Data Warehouse Database Management System Magic Quadrant. Gartner’s 2009 data warehouse DBMS Magic Quadrant — actually, January 2010 — is now out.* For many reasons, including those I noted in my comments on Gartner’s 2008 Data Warehouse DBMS Magic Quadrant, the Gartner quadrant pictures are a bad use of good research. Rather than rehash that this year, I’ll merely call out some points in the surrounding commentary that I find interesting or just plain strange. Read more
The Sybase Aleri RAP
Well, I got a quick Sybase/Aleri briefing, along with multiple apologies for not being prebriefed. (Main excuse: News was getting out, which accelerated the announcement.) Nothing badly contradicted my prior post on the Sybase/Aleri deal.
To understand Sybase’s plans for Aleri and CEP, it helps to understand Sybase’s current CEP-oriented offering, Sybase RAP. So far as I can tell, Sybase RAP has to date only been sold in the form of Sybase RAP: The Trading Edition. In that guise, Sybase RAP has been sold to >40 outfits since its May, 2008 launch, mainly big names in the investment banking and stock exchange sectors. If I understood correctly, the next target market for Sybase RAP is telcos, for real-time network tuning and management.
In addition to any domain-specific applications, Sybase RAP has three layers:
- CEP (Complex Event Processing). Sybase RAP CEP is based on a version of the Coral8 engine Sybase licensed and has been subsequently developing.
- In-memory DBMS. Sybase’s IMDB is part of (but I guess separable from) and has the same API as Sybase’s OLTP DBMS Adaptive Server Enterprise (ASE, aka Sybase Classic).
- Sybase IQ. Actually, Sybase used the phrase “based on Sybase IQ,” but I’m guessing it’s just Sybase IQ.
Quick thoughts on Sybase/Aleri
Sybase announced an asset purchase that amounts to a takeover of CEP (Complex Event Processing) Aleri. Perhaps not coincidentally, Sybase already had technology under the hood from Aleri predecessor/acquiree Coral8, for financial services uses (notwithstanding that between Aleri Classic and Coral8, Aleri Classic was the one of the two more focused on financial services). Quick reactions include:
- The folks at Sybase still haven’t figured out when to prebrief me. (Edit: I’ve been briefed subsequently.)
- Sybase/Aleri is a potentially powerful combination, if they can effectively address the point I just made about integrating disparate latencies. That said, I’m not expecting a lot, because the CEP industry always disappoints me.
- Microsoft, IBM, and (somewhat less clearly) Oracle are all trying to do CEP inhouse. Sybase is making a good choice in having serious CEP inhouse itself
- Surely the main focus and financial justification for the Sybase/Aleri acquisition is the financial services market.
- Specifically, I expect the focus of technical integration between Aleri and Sybase’s DBMS products to start with Sybase IQ.
- Coral8 had some interesting ideas about how to integrate CEP with OLTP/operational BI, but I’m not aware that they got much traction.
- I bet there are use cases where Sybase tries and fails to sell Adaptive Server SQL Anywhere that CEP would be a better technical fit, but I don’t immediately see much practical business significance to that observation.
- While this deal could easily strengthen the Vertica/StreamBase partnership, I don’t see any reason why it would lead those two companies to actually merge.
