Toon is a member of Oracle’s Real-World Performance team. The RWP-team assist 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 these performance issues. Prior to joining the RWP team, Toon has been mainly involved in database application development. His special interests are: architecting applications for performance and scalability, database design, business rules / constraints modelling (see his proposal for support for SQL assertions https://community.oracle.com/ideas/13028 ), and the Smart Database paradigm ( https://www.youtube.com/playlist?list=PLdtXkK5KBY56RKLbtH4-wyDvZhe7UZ1bB ). He has been part of the Oracle ecosystem since 1987, is a member of the Oaktable, and ACED-alumni.
