Who is doing what in XML data management these days?
A comment thread to a post on a different subject has opened up a discussion of XML storage. Frankly, I haven’t kept up with my briefings on the subject, in part because XML support hasn’t proved to be very important yet to the big DBMS vendors, somewhat to my surprise. When last I looked, the situation wasn’t much different from what it was back in November, 2005. Unless I’ve missed something (and please tell me if I have!), here’s what’s going on: Read more

Oracle’s hefty price increases
Jeff Jones of IBM wrote in to point out that Oracle is slathering on the price increases. I quote: Read more

ANTs bails out of the DBMS market
ANTs Data Server — i.e., the ANTs DBMS — has been sold off to a company called 4Js. It is now to be called Genero DB. Actually, 4Js has been selling or working on a version of the product called Genero DB since 2006, specifically an Informix-compatible one.
I’m not totally clear on why an Informix-compatible DBMS is needed in a world that already has Informix SE, but maybe IBM is overcharging for maintenance even on the low-end version of the product.
Meanwhile, ANTs, which had originally tried to get enterprises to migrate away from Oracle, is now focused on middleware called the ANTs Compatibility Server to help them migrate to Oracle, specifically/initially from Sybase.

Truviso and EnterpriseDB blend event processing with ordinary database management
Truviso and EnterpriseDB announced today that there’s a Truviso “blade” for Postgres Plus. By email, EnterpriseDB Bob Zurek endorsed my tentative summary of what this means technically, namely:
There’s data being managed transactionally by EnterpriseDB.
Truviso’s DML has all along included ways to talk to a persistent Postgres data store.
If, in addition, one wants to do stream processing things on the same data, that’s now possible, using Truviso’s usual DML.
Supporting evidence for the DBMS disruption story
As previously announced, I did a webcast this afternoon, discussing database diversity. The title of the talk was taken directly from a post – What leading DBMS vendors don’t want you to realize — that argued mid-range DBMS are suitable for a broad variety of tasks. The overriding theme was a Clayton Christensen-style “disruption” narrative.
The sponsor was EnterpriseDB, which is fitting. While not the biggest DBMS industry disrupter in terms of revenue or visible impact (MySQL and Netezza say “Hi”), the Postgres family in general and EnterpriseDB in particular epitomize the disruption threat like nobody else, because of how broadly they substitute for market-leading database managers.
As I promised on the call, below is a post with links to further research backing up the points made. They’re numbered to match some of the presentation slides, which you can find at this link.
3. Much of the discussion of database diversity comes from a series of posts I coordinated with Mike Stonebraker.
4. At various times, starting on Slide 4, I made reference to datatype extensibility, a key feature of Oracle and DB2 – and a key advantage of Postgres over MySQL.
10. Capping off the database diversity discussion, Slide 10 mirrors this 11-point version of a data management software taxonomy.
13-14. I’ve posted many times about data warehousing DBMS and related technologies, including this overview of major analytic DBMS products, another recent overview of data warehouse specialty technologies, and an attempt to distinguish between data warehouse appliance myths and realities. Of particular interest for further research may be our sections on data warehouse appliances and columnar DBMS.
15. I do most of my posting about text search over on Text Technologies, specifically in the search category. Vendors I specifically mentioned as blending search with other kinds of data retrieval were Mark Logic and Attivio.
16. There’s a section here on native XML database management.
17. We also have a section on managing RDF and other graphical data models.
18. Ditto complex event/stream processing.
19. The only embeddable DBMS I’ve written much about recently is solidDB. And frankly, even in that case I’ve focused more on mid-tier caching uses, the now-canceled MySQL relationship, or general technology than I did specifically on embedded uses.
22-24. Back in February, 2007 I made what is probably still my clearest post explaining why I think market-leading DBMS vendors are in the process of getting disrupted

Positioning the data warehouse appliances and specialty DBMS
There now are four hardware vendors that each offer or seem about to announce two different tiers of data warehouse appliances: Sun, HP, EMC, and Teradata. Specifically:
-
Sun partners with both Greenplum and ParAccel.
-
HP sells Neoview, and also is partnered with Vertica.
-
EMC (together with Dell in North America and Bull in Europe) sells DATAllegro. Now EMC is also entering a partnership with ParAccel.
-
Teradata is pretty far down the road toward releasing a low-end product.
Data warehousing with paper clips and duct tape
An interesting part of my conversation with Dataupia’s CTO John O’Brien came when we talked about data warehousing in general. On the one hand, he endorsed the view that using Oracle probably isn’t a good idea for data warehouses larger than 10 terabytes, with SQL Server’s limit being well below that. On the other hand, he said he’d helped build 50-60 terabyte warehouses in Oracle years ago.
The point is that to build warehouses that big in Oracle or other traditional DBMS, you have to pull out a large bag of tricks. Read more

Who is actually using native XML?
Question of the day #2
Who is actually using native XML?
Mark Logic is having a fine time using its native XML engine for custom publishing. One outfit I know of is using a native XML for something like web analytics, but is driving me crazy by never coming through on permission to divulge details. There’s a bit of native XML use out there supporting the insurance industry’s ACORD standard.
And after that I quickly run out of examples of native XML use. Read more

Is anybody actually using image, video, or sound indexing?
I have quite the excess of “flu-like symptoms,” and nothing substantive I’m writing today is coming to fruition. So instead of forcing the issue, I’m going to put a few questions out for discussion.
Question of the day #1
Is anybody indexing the actual contents of still images, video, or sound files?
Obviously, there are applications that serve huge numbers of videos, pictures, and/or songs — YouTube, Flickr, iTunes, and so on. But generally, these media are just handled as files or BLOBs, while all the database indexing is on alphanumeric metadata such as title, tags, uploader, date, download stats, comments, and so on.
The technology certainly exists to be more sophisticated. Consider, for example, Oracle’s Still Image datatype, which in typical Oracle fashion implements the relevant parts of SQL/MM and goes yet further. Read more

14 reasons not to use MySQL or other mid-range database management systems
I may argue for the use of open source and other mid-range database management systems, but a lot of industry sentiment remains on the other side. Vendors of high-end RDBMS naturally advocate enterprise-wide single-vendor adoption. Many CIOs and industry analysts, overwhelmed by product proliferation, think that’s a neat idea as well.
And in fairness, they’re not entirely wrong. Here are 14 reasons for using high-end relational database management systems, even on applications for which mid-range DBMS would suffice. Read more
