The reference to MySQL is very out of date. It seems that most people's understanding of MySQL's capabilities is mired in MySQL 3.x. Philip mentions that his information is current "circa 2003" but quite a lot has changed since then. For OLTP and enterprise grade applications, the stable now includes:
- MySQL 4.0, with InnoDB ACID-compliant storage engine
- MySQL 5.0, with InnoDB and standards compliant stored procedures, triggers, views, etc.
- MaxDB, formerly SAP DB, "a heavy-duty, SAP-certified open source database for OLTP and OLAP usage".
