InnoDB

From Oracle FAQ

InnoDB is a transaction-safe (ACID compliant) storage engine with foreign key support along with commit, rollback, and crash recovery capabilities.

InnoDB is not a standalone database product, but is distributed as a part of the MySQL database. Also see Berkeley DB.

History

InnoDB was first released as a part of MySQL in 2001.

MySQL had a licensing agreement with Innobase which enabled them to provide InnoDB under a commercial license to paying customers, alongside the distribution as a GPL (open source and free as in beer) product.

In October 2005, Oracle purchased the Finland-based Innobase Oy. Since then, MySQL renewed the contract with Oracle Corporation.
