Oracle Nederland BV
Toon is a member of Oracle's Real-World Performance (RWP) team, which assists in diagnosing application performance issues in and around the DBMS. The way applications currently use—or rather, abuse—the DBMS is often at the root of performance issues.
Before joining the RWP team, Toon was involved in database application development. His special interests include architecting applications for performance/scalability and relational database design. He has been part of the Oracle eco-system since 1987, is a member of the Oaktable, and occasionally tweets at @ToonKoppelaars.
