I've always greatly admired the DBA toolkit, and found the criticism of Mr Wooton very amusing. Well, I assume it was tongue-in-cheek. Even if it wasn't useful, it is great to illustrate that it can be done.
One point he's right about. SQL Server works very well in a Unix\J2EE environment thanks to its rather good JDBC driver. Of course, the database server itself has to run on Windows, but that is only a problem to the fanatics.
Best wishes,
