## Key Advantages of InnoDB 

•Its DML operations follow the ACID model, with transactions featuring commit, rollback, and crash- recovery capabilities to protect user data. See Section 15.2, “InnoDB and the ACID Model” . 

•Row-level locking and Oracle-style consistent reads increase multi-user concurrency and performance. See Section 15.7, “InnoDB Locking and Transaction Model” . 

• InnoDB  tables arrange your data on disk to optimize queries based on primary keys. Each InnoDB  table has a primary key index called the clustered index that organizes the data to minimize I/O for primary key lookups. See Section 15.6.2.1, “Clustered and Secondary Indexes” . 

•To maintain data integrity, InnoDB  supports FOREIGN KEY  constraints. With foreign keys, inserts, updates, and deletes are checked to ensure they do not result in inconsistencies across related tables. See Section 13.1.20.5, “FOREIGN KEY Constraints” .
