InnoDB is a very popular database engine for the MySQL DBMS. It is an alternative to the default MyISAM engine and it has lots of strong sides that have made it the preferred engine for a lot of open-source script-powered software apps, such as Joomla™ and Magento, which have shifted over to InnoDB for good. For instance, adding enormous volumes of data will be much faster with InnoDB, because it locks only one database row to accomplish a specific operation, not the entire 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 info is treated. Put simply, appending new or editing existing data will either be thoroughly completed, or will be annulled and the operation will be rolled back if any issue appears in the meantime, which means that the content that remains in the database won’t be lost.
