Document-oriented DBMS without joins

When I talked with MarkLogic’s Ken Chestnut about MarkLogic 4.2, I was surprised to learn that MarkLogic really, truly doesn’t do anything like a join. Unlike some other non-SQL DBMS, MarkLogic has no SQL interface, no ODBC or JDBC. Nothing, nada. (MarkLogic has a Java interface for Xquery, but not for anything like SQL.)

MarkLogic and its document DBMS

This post has been long in the writing for several reasons, the biggest being that I stopped working for almost a month due to family issues. Please forgive its particularly choppy writing style; having waited this long already, I now lack the patience to further clean it up.

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.

HP. Neoview will never succeed. Admit it to yourselves. Go buy something that can.  Read more

MarkLogic architecture deep dive

While I previously posted in great detail about how MarkLogic Server is an ACID-compliant XML-oriented DBMS with integrated text search that indexes everything in real time and executes range queries fairly quickly, I didn’t have a good feel for how all those apparently contradictory characteristics fit into a single product. But I finally had a call with Mark Logic Director of Engineering Ron Avnur, and think I have a better grasp of the MarkLogic architecture and story.

Ron described MarkLogic Server as a DBMS for trees. Read more

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

The Mark Logic story in XML database management

Mark Logic* has an interesting, complex story. They sell a technology stack based on an XML DBMS with text search designed in from the get go. They usually want to be known as a “content” technology provider rather than a DBMS vendor, but not quite always.

*Note: Product name = MarkLogic, company name = Mark Logic.

I’ve agreed to do a white paper and webcast for Mark Logic (sponsored, of course). But before I start serious work on those, I want to blog based on what I know. As always, feedback is warmly encouraged.

Some of the big differences between MarkLogic and other DBMS are:

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
