Recover Data Even After Encountering Error Code 1030 in MySQL Database

InnoDB and MyISAM both are default storage engines of MySQL database management system. However, database administrators prefer InnoDB over MyISAM as InnoDB provides ACID compatible transaction environment, and facilitates features like crash recovery, rollback, and commit.
