As the default storage engine for MySQL, MyISAM provides a good balance between performance and available features

These features include full-text retrieval, compression, and spatial functions. MyISAM does not support transaction and row-level locks.

This is because the MySQL version of the book has not reached 5.1 yet.

InnoDB is a general-purpose storage engine that balances high reliability and high performance. Starting from MySQL 5.5.5, the default storage engine for new tables is InnoDB rather than MyISAM. Unless you have configured a different default storage engine, issuing a CREATE TABLE statement without an ENGINE= clause creates an InnoDB table. Given this change of default behavior, MySQL 5.5 might be a logical point to evaluate whether tables that use MyISAM could benefit from switching to InnoDB.

After 5.5.5, InnoDB has become the default storage engine for MySQL

InnoDB includes all the features that were part of the InnoDB Plugin for MySQL 5.1, plus new features specific to MySQL 5.5 and higher.
