Innodb is the new storage engine used now-a-days for MySQL database. This storage engine has numerous advancements over other storage engines. These advancements are as follows:

• Innodb provides Atomicity, Consistency, Isolation, Durability (ACID) compliant transaction support, which enables all the database transactions to proceed reliably.
• Innodb is quite similar to PostgreSQL. It also allows blocks of code to be successfully executed by the server.
• Innodb also provides foreign key support (declarative referential integrity).

InnoDB - a product of Oracle - has numerous features, discussed as follows:

• InnoDB offers greater perceived availability and reliability as database sizes grow.
• Innodb is substantially faster than MyISAM in some situations.
