InnoDB vs MyISAM

InnoDB has row-level locking. MyISAM only has full table-level locking. InnoDB has what is called referential integrity which involves supporting foreign keys (RDBMS) and relationship constraints, MyISAM does not (DMBS). InnoDB supports transactions, which means you can commit and roll back.
