- My Top Ten Assertions About Data Warehouses (CACM) — Michael Stonebraker’s take on the data warehouse world, and his predictions cut across a lot of our O’Reilly trends.

[…] Almost all DBMSs have 100 or more complicated tuning “knobs.” This requires DBAs to be “4-star wizards” and drives up operating costs. Obviously, the only thing that makes sense is to have a program that adjusts these knobs automatically. In other words, look for “no knobs” as the only way to cut down DBA costs.
