For anyone familiar with Oracle but potentially interested in MySQL (hosted on, here is a good bit of comparative information.  At <>, you'll find a PDF of the presentation "MySQL for Oracle DBAs and Developers" given at last week's MySQL Conference & Expo 2007.  It gives an overview of similarities and differences, explains how to migrate from Oracle to MySQL, and provides links to further information.  Note that some information presented is specific to MySQL >= 5.0, which we will be upgrading to later this month.
