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
