              Are analytic RDBMS and data warehouse appliances obsolete?

              I used to spend most of my time — blogging and consulting alike — on data warehouse appliances and analytic DBMS. Now I’m barely involved with them. The most obvious reason is that there have been drastic changes in industry structure:

              Simply reciting all that, however, begs the question of whether one should still care about analytic RDBMS at all.

              My answer, in a nutshell, is:

              Analytic RDBMS — whether on premises in software, in the form of data warehouse appliances, or in the cloud — are still great for hard-core business intelligence, where “hard-core” can refer to ad-hoc query complexity, reporting/dashboard concurrency, or both. But they aren’t good for much else.

              Layering of database technology & DBMS with multiple DMLs

              Two subjects in one post, because they were too hard to separate from each other

              Any sufficiently complex software is developed in modules and subsystems. DBMS are no exception; the core trinity of parser, optimizer/planner, and execution engine merely starts the discussion. But increasingly, database technology is layered in a more fundamental way as well, to the extent that different parts of what would seem to be an integrated DBMS can sometimes be developed by separate vendors.

              Major examples of this trend — where by “major” I mean “spanning a lot of different vendors or projects” — include:

              Other examples on my mind include:

              And there are several others I hope to blog about soon, e.g. current-day PostgreSQL.

              In an overlapping trend, DBMS increasingly have multiple data manipulation APIs. Examples include:? Read more

              Comments on Gartner’s 2012 Magic Quadrant for Data Warehouse Database Management Systems — evaluations

              To my taste, the most glaring mis-rankings in the 2012/2013 Gartner Magic Quadrant for Data Warehouse Database Management are that it is too positive on Kognitio and too negative on Infobright. Secondarily, it is too negative on HP Vertica, and too positive on ParAccel and Actian/VectorWise. So let’s consider those vendors first.

              Gartner seems confused about Kognitio’s products and history alike.

              Gartner is correct, however, to note that Kognitio doesn’t sell much stuff overall.

              * non-existent

              In the cases of HP Vertica, Infobright, ParAccel, and Actian/VectorWise, the 2012 Gartner Magic Quadrant for Data Warehouse Database Management’s facts are fairly accurate, but I dispute Gartner’s evaluation. When it comes to Vertica: Read more

              Further thoughts on previous posts

              One thing I love about DBMS 2 is the really smart comments a number of readers — that would be you guys — make. However, not all the smart comments are made in the first 5 minutes a post is up, so some readers (unless you circle back) might miss great points other readers make. Well, here are some pointers to some of what you might have missed, along with other follow-up comments to old posts while I’m at it. Read more

              Calpont’s InfiniDB

              Since its inception, Calpont has gone through multiple management teams, strategies, and investor groups. What it hadn’t done, ever, is actually shipped a product. Last week, however, Calpont introduced a free/open source DBMS, InfiniDB, with technical details somewhat reminiscent of what Calpont was promising last April. Highlights include:

              Being on vacation, I’ll stop there for now. (If it weren’t for Tropical Storm/ depression Ida, I might not even be posting this much until I get back.)

              Daniel Abadi on Kickfire and related subjects

              Daniel Abadi has a new blog, whose first post centers around Kickfire.? The money quote is (emphasis mine):

              In order for me to get excited about Kickfire, I have to ignore Mike Stonebraker’s voice in my head telling me that DBMS hardware companies have been launched many times in the past are ALWAYS fail (the main reasoning is that Moore’s law allows for commodity hardware to catch up in performance, eventually making the proprietary hardware overpriced and irrelevant). But given that Moore’s law is transforming into increased parallelism rather than increased raw speed, maybe hardware DBMS companies can succeed now where they have failed in the past

              Good point.

              More generally, Abadi speculates about the market for MySQL-compatible data warehousing.? My responses include:

              Anyhow, as previously noted, I’m a big Daniel Abadi fan. I look forward to seeing what else he posts in his blog, and am optimistic he’ll live up to or exceed its stated goals.

              Calpont update — you read it here first!

              Calpont has gone through a lot of strategy iterations since its founding. The super-short version is that Calpont originally planned an appliance built around a SQL chip, much like Kickfire. But after various changes in management and venture backing, Calpont turned itself into a software-only analytic DBMS vendor relying on a MySQL front end. Calpont is now at the stage of announcing an Early Adopter program at the MySQL conference on Wednesday, although details of Calpont’s product release timing, pricing, feature set, etc. are all To Be Determined.

              Minor highlights of the Calpont technical story include: Read more
