I’m back from a trip to the SF Bay area, with a lot of writing ahead of me. I’ll dive in with some quick comments here, then write at greater length about some of these points when I can. From my trip: Read more
Advice for some non-clients
Edit: Any further anonymous comments to this post will be deleted. Signed comments are permitted as always.
Most of what I get paid for is in some form or other consulting. (The same would be true for many other analysts.) And so I can be a bit stingy with my advice toward non-clients. But my non-clients are a distinguished and powerful group, including in their number Oracle, IBM, Microsoft, and most of the BI vendors. So here’s a bit of advice for them too.
Oracle. On the plus side, you guys have been making progress against your reputation for untruthfulness. Oh, I’ve dinged you for some past slip-ups, but on the whole they’ve been no worse than other vendors.’ But recently you pulled a doozy. The analyst reports section of your website fails to distinguish between unsponsored and sponsored work.* That is a horrible ethical stumble. Fix it fast. Then put processes in place to ensure nothing that dishonest happens again for a good long time.
*Merv Adrian’s “report” listed high on that page is actually a sponsored white paper. That Merv himself screwed up by not labeling it clearly as such in no way exonerates Oracle. Besides, I’m sure Merv won’t soon repeat the error — but for Oracle, this represents a whole pattern of behavior.
Oracle. And while I’m at it, outright dishonesty isn’t your only unnecessary credibility problem. You’re also playing too many games in analyst relations.

New insights into the GPL vs. MySQL storage engine debates
Around the time of Oracle’s acquisition of Sun and hence MySQL, there was a lot of discussion as to whether MySQL’s GPL license could inhibit MySQL storage engine vendors from selling their products without MySQL code (e.g., with MySQL-fork front-ends). I argued No. Most people, however, seemed to think “Yes, and even if the matter isn’t clear, the threat of nasty lawyers creates enough FUD to be a practical market problem for the storage engine vendors.” Based on those concerns, I eventually took the position that Oracle should be inhibited for antitrust reasons from invoking its real or alleged GPL rights to mess with the MySQL storage engine vendors. Oracle’s agreement with the EU alleviated that concern, except that there was an annoying time limit on the alleviation.
Now a related can of worms has been opened in a related technology area — WordPress and WordPress themes. Since many bloggers use WordPress, this has gotten a lot of attention, and some interesting new insights have emerged. Read more

Breakthrough: Exadata now has as many reference accounts as Aster Data!
According to Bob Evans of Information Week, there now are 15 disclosed Exadata reference accounts. Coincidentally, there are exactly 15 logos on Aster Data’s customer page. So on it own, that’s not a particularly impressive piece of information.
But other highlights of his column include:
- Some of those accounts are rather big-name. However, I’m not at all sure whether they’re actual production references.
- Andy Mendelsohn characterizes the sweet spot of Exadata’s market as “virtual private cloud.” That matches what Juan Loaiza told me six months ago.
- Oracle claims numerous competitive wins for Exadata. Let me hasten to note that one vendor’s “competitive win” is another vendor’s “our salesman read the deal as an unfavorable one and chose not to compete,” or even sometimes “Huh? We never heard about that deal.” That said, what I’m hearing is that Exadata is indeed a much stronger competitor than it used to be.
- Oracle claims a near $1 billion sales run rate for Exadata. No doubt, a large majority of those are hardware upgrades for existing Oracle database customers, often from non-Sun/Oracle hardware. Even so, some of those are surely deals that would have migrated away from Oracle in the pre-Exadata past.

Netezza’s version of EnterpriseDB-based Oracle compatibility
EnterpriseDB has some deplorable business practices (my stories of being screwed by EnterpriseDB have been met by “Well, you’re hardly the only one”). But a couple of more successful DBMS vendors have happily partnered with EnterpriseDB even so, to help pick off Oracle users. IBM’s approach was in the vein of an EnterpriseDB-infused version of SQL handling within DB2.* Netezza just announced an EnterpriseDB-based Netezza Migrator that is rather different.
*The comment threads are the most informative parts of those posts.
I’m a little unclear as to the Netezza Migrator details, not least because Netezza folks don’t seem to care too much about Netezza Migrator themselves. That said, the core ideas of Netezza Migrator are: Read more

Best practices for analytic DBMS POCs
When you are selecting an analytic DBMS or appliance, most of the evaluation boils down to two questions:
- How quickly and cost-effectively does it execute SQL?
- What analytic functionality, SQL or otherwise, does it do a good job of executing?
And so, in undertaking such a selection, you need to start by addressing three issues:
- What does “speed” mean to you?
- What does “cost” mean to you?
- What analytic functionality do you need anyway?

Various quick notes
As you might imagine, there are a lot of blog posts I’d like to write I never seem to get around to, or things I’d like to comment on that I don’t want to bother ever writing a full post about. In some cases I just tweet a comment or link and leave it at that.
And it’s not going to get any better. Next week = the oft-postponed elder care trip. Then I’m back for a short week. Then I’m off on my quarterly visit to the SF area. Soon thereafter I’ve have a lot to do in connection with Enzee Universe. And at that point another month will have gone by.
Anyhow: Read more

ITA Software and Needlebase
Rumors are flying that Google may acquire ITA Software. I know nothing of their validity, but I have known about ITA Software for a while. Random notes include:
- ITA Software builds huge OLTP systems that it runs itself on behalf of airlines.
- Very, very unusually, ITA Software builds these huge OLTP systems in LISP.
- ITA Software is an Oracle shop (see Dan Weinreb’s comment).
- ITA Software is run by a techie (again, see Dan Weinreb’s comment).
- ITA Software has an interesting screen-scraping/web ETL project called Needlebase
ITA’s software does both price/reservation lookup/checking and reservation-making. I’ve had trouble keeping it straight, but I think the lookup is ITA’s actual business, and the reservation-making is ITA’s Next Big Thing. This is one of the ultimate federated-transaction-processing applications, because it involves coordinating huge OLTP systems run, in some cases, by companies that are bitter competitors with each other. Network latencies have to allow for intercontinental travel of the data itself.
Indeed, airline reservation systems are pretty much the OLTP ultimate in themselves. As the story goes, transaction monitors were pretty much invented for airline reservation systems in the 1960s.
A really small project for ITA Software is Needlebase. I stopped by ITA to look at Needlebase in January, and what it is is a very smart and hence interesting screen-scraping system. The idea is people publish database information to the web, and you may want to look at their web pages and recover the database records it is based on. Applications of this to the airline industry, which has 100s of 1000s of price changes per day — and I may be too low by one or two orders of magnitude when I say that — should be fairly obvious. ITA Software has aspirations of applying Needlebase to other sectors as well, or more precisely having users who do so. Last I looked, ITA hadn’t put significant resources behind stimulating Needlebase adoption — but Google might well change that.
Edit: I just re-found an old characterization of (some of) what ITA Software does by — who else? — Dan Weinreb:
I am working on our new product, an airline reservation system. It’s an online transaction-processing system that must be up 99.99% of the time, maintaining maximum response time (e.g. on www.aircanada.com). It’s a very, very complicated system. The presentation layer is written in Java using conventional techniques. The business rule layer is written in Common Lisp; about 500,000 lines of code (plus another 100,000 or so of open source libraries). The database layer is Oracle RAC. We operate our own data centers, some here in Massachusetts and a disaster-recovery site in Canada (separate power grid).

Story of an analytic DBMS evaluation
One of our readers was kind enough to walk me through his analytic DBMS evaluation process. The story is:
- The X Company (XCo) has a <1 TB database.
- 100s of XCo’s customers log in at once to run reports. 50-200 concurrent queries is a good target number.
- XCo had been “suffering” with Oracle and wanted to upgrade.
- XCo didn’t have a lot of money to spend. Netezza pulled out of the sales cycle early due to budget (and this was recently enough that Netezza Skimmer could have been bid).
- Greenplum didn’t offer any references that approached the desired number of concurrent users.
- Ultimately the evaluation came down to Vertica and ParAccel.
- Vertica won.
Notes on the Vertica vs. ParAccel selection include: Read more
