He seems to have a tendency to represent the worst possible uses of various things as typical usage, and ignore a number of useful things.

For example, he claims that the security uses of stored procedures have been replaced by role based access control. That's incorrect. If you want to audit changes to a table using RBAC then the user not only needs access to the audit table but must always update it themselves. A user could easily cover up changes by simply omitting the audit row, or adding false data. The use of triggers and stored procedures can enforce the audit, and protect it from malicious update.

His claim that triggers are a bad idea because a novice DBA once disabled them on a production database, not realising that they existed, is just silly. The fix is to ensure that people get a clue before they get superuser access! Triggers are a standard part of every big modern database, and a standard part of any training program.

I could go on, but I don't really fancy debunking every silly thing people write about databases...
