Storage engines
Many of the modern DBMS support multiple storage engines within the same database . For example , MySQL supports InnoDB as well as MyISAM . Some storage engines are transactional .
A database engine (or storage engine) is the underlying software component that a database management system (DBMS) uses to create, read, update and delete (CRUD) data from a database. Most database management systems include their own application programming interface (API) that allows the user to interact with their underlying engine without going through the user interface of the DBMS. The term database engine is frequently used interchangeably with database server or database management system. A 'database instance' refers to the processes and memory structures of the running database engine.
