Extensible Storage Engine (ESE, EDB, ESEDB), also known as JET Blue (no connection with the airline) is a database engine from Microsoft used as the back-end database of a number of its products, and eventually a public API was released for it. .edb and .sdb files are used for database storage, and .stm for a streaming file. There are a number of different versions.

The method of database storage is ISAM (Indexed Sequential Access Method).

An earlier and slightly different Microsoft database engine is Jet Red, which supports file sharing.
