Michael, The reason you think there's not much to this database is that compared to Oracle, there really is not much to this database. :-)
>From a 50,000-foot point of view, it's really just a nice SQL interface to ISAM files (it started out that way, anyway). It is designed for high-performance in read-intensive environments, and so it doesn't really need to be that complicated. MySQL is a single-process, multithreaded server. That means you start mysqld through the wrapper script and that's all that runs. It doesn't have separate specialized daemons for doing various tasks like Oracle and PostgreSQL do. All data is stored in MyISAM files (assuming you're not using InnoDB or BDB), two per table (one data, one index file), and tables are stored in directories corresponding to the database name in the configured data directory. Some basic knowledge of system performance tuning for your given OS and reading the manual, particularly Chapter 5 (MySQL Optimization) should put you well ahead of the pack.
