Empress Embedded Database:
Empress Software, developers of the Empress Embedded Database, is a privately held company founded in 1979. ^[1]. Empress Embedded Database is a full-function, relational database that has been embedded into applications by organizations small to large, including medical systems, network routers, nuclear power plant monitors, satellite management systems, and other embedded system applications that require reliability and power. ^[2].

Oracle Berkeley DB:
As the name implies, Oracle’s embedded database is actually Berkeley DB, which Oracle acquired from Sleepycat Software and was originally developed at the University of California. ^[3] Berkeley DB is an fast, open-source embedded database and is used in several well-known open-source products, including the Linux and BSD Unix operating systems, Apache Web server, OpenLDAP directory, and OpenOffice productivity suite. ^[4].
