InnoDB is a very popular database storage engine for the MySQL DBMS. It is an alternative to the default MyISAM engine and it has plenty of strengths which make it the preferred engine for a lot of PHP script-powered applications, including Joomla™ and Magento, which have moved to InnoDB for good. For example, adding immense data volumes will be much faster with InnoDB, as it locks only a single database row to carry out a certain task, not the entire database table, which makes the engine excellent for scalable applications. It also supports foreign keys and database transactions – these refer to the way in which the data is treated. Simply put, importing new or editing existent data will either be thoroughly completed, or will be aborted and the procedure will be rolled back if a given problem appears during the process, so the content that remains in the database won’t be damaged.
