Polyhedra
Polyhedra PLC
Milton Keynes U.K.; 190-836-6844
A memory resident ORDBMS suitable for developing multiuser client/server distributed applications that require a high degree of real-time information. The database is internally object-oriented with program scripts for object methods using a built-in 4GL language, allowing the database to become an active component in any application. The database is capable of communicating directly and actively with other databases, systems, and external "rapid data set" devices, allowing integration of many disparate systems into a single coherent application. A concept called active queries allows connected clients to specify the data requirements in terms of SQL; the database then returns the resultant data set, subsequently informing the client of any changes to the data set whenever the database contents change in such a manner as to affect the result of the initial query. Other features include full class inheritance and many data types including variable-length strings and BLOBS. The database supports full cross-platform support, persistence on demand, fault tolerance, high-speed historical data logging, and recall, with ODBC and DDE support. The product also supports an event-driven interface to standard RDBMSs. Platforms include most Unix variants, Windows NT, Windows 95, and embedded RTOS's (pSOS+ and so on). Prices start at $1900.
