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.[2] 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.
