Oracle Versus MySQL Classes

I'm always being asked what is the difference between Oracle classes and MySQL classes. What are the similarities and what are some of the differences? So I thought I'd jot down a few notes.

Course similarities:

Oracle Classes	MySQL Classes
Oracle Database 11g: Introduction to SQL	MySQL for Beginners
Oracle Database 11g: Introduction for Exp. SQL Users	MySQL for Developers
Oracle Database 11g: SQL Fundamentals II	MySQL Developer Techniques
Oracle Database 11g: PL/SQL Developer	MySQL Stored Procedures Techniques
Oracle Database 11g: Administrator Workshop I	MySQL for DBAs
Oracle Database 11g: Performance Tuning	MySQL Performance Tuning
Oracle Database 11g: RAC Administration	MySQL Cluster

Notes on some differences:
Oracle RAC (MySQL Cluster), PL/SQL (MySQL Stored Procedures), Streams (MySQL HA) have a lot more depth and complexity than MySQL equivalents.
MySQL does not have a class for MySQL Enterprise Monitor (Oracle Grid).
MySQL has PHP class, while Oracle has Java, Fusion Middleware, APEX and Forms developer classes
