InnoDB
InnoDB is a storage engine for the database management system MySQL and MariaDB.[1] Since the release of MySQL 5.5.5 in 2010, it replaced MyISAM as MySQL's default table type.[2][3] It provides the standard ACID-compliant transaction features, along with foreign key support (Declarative Referential Integrity). It is included as standard in most binaries distributed by MySQL AB, the exception being some OEM versions.
