Polyhedra is a family of relational database management systems offered by ENEA AB, a Swedish company. The original version of Polyhedra (now referred to as Polyhedra IMDB) was an in-memory database management system which could be used in high availability configurations; in 2006 Polyhedra Flash DBMS was introduced to allow databases to be stored in flash memory. All versions employ the client–server model to ensure the data are protected from misbehaving application software, and they use the same SQL, ODBC and type-4 JDBC interfaces. Polyhedra is targeted primarily for embedded use by Original Equipment Manufacturers (OEMs), and big-name customers include Ericsson, ABB, Emerson, Lockheed Martin, United Utilities and Siemens AG.
