Long, confused overview of data warehouse DBMS vendors
Steven Swoyer has an article for Enterprise Systems that covers a lot of issues in data warehouse technology. Unfortunately, however, it doesn’t always cover them correctly. E.g., he seems to imply that columnar architectures aren’t relational. (Oops.) I wouldn’t put too much credence in the other market segmentations he posits either.
Some of his theses, however, are basically correct. E.g., he points out that demand for fast, cost-effective, (almost) unconstrained ad hoc queries keeps growing, and that much of the recent innovation is concerned with supplying them.

I’ve had similar concerns about Swoyer’s reporting in the past. But for this article, in particular, he was way out of his depth.
