Enea Embedded Technology Introduces Polyhedra Database for LynxOS, Windows 2003 and Solaris 9; Polyhedra 5.1 Offers Enhanced Performance and Broadens Platform Support.

TEMPE, Ariz. & STOCKHOLM, Sweden -- Enea Embedded Technology (SAXESS:ENEA) today introduced version 5.1 of its Polyhedra(TM) relational database management solution (RDBMS). Now available for the LynxOS embedded operating system for Windows Server 2003, Solaris 9 and VxWorks 5.5, Polyhedra 5.1 offers integral performance enhancements that bring the speed advantages of an in-memory database to Java programmers. The extension of Polyhedra's platform support illustrates Enea's ongoing commitment to making the database available for a wide variety of operating systems.

Polyhedra 5.1 fully compatible with earlier Polyhedra versions, and is available for previously supported platforms, including Windows, Linux, Solaris 8, AIX, VxWorks 5.4 and Enea's OSE operating system.

"With the additional support for LynxOS, Enea Embedded Technology is once again emphasizing its strategy of extending Polyhedra's availability to a broad variety of operating systems in the embedded and server-level space," said Nigel Day, product manager for Polyhedra at Enea Embedded Technology. "Polyhedra is ideal for a wide variety of embedded applications that require fast time-to-market, high performance, enhanced reliability and reduced lifetime support costs."

Polyhedra is a real-time, fault-tolerant, active, in-memory relational database, primarily designed for embedded applications such as process-control, telemetry, remote monitoring, telecommunications and data communications. It can also be utilized in server-level systems to provide high-performance active database support for applications such as mission control. Polyhedra is also used in financial areas for dynamically monitoring, validating and analyzing data feeds.

Polyhedra 5.1 brings fundamental performance enhancements to database users. Featuring a small code footprint, Polyhedra uses a memory-resident design that boosts performance by an order of magnitude relative to conventional disk-based RDBMSs, without sacrificing data security. In version 5.1, the database management system and the JDBC (Java Database Connectivity) driver have been tuned to ensure that, depending on the efficiency of the Java runtime system in use, the database performance available to Java programmers is close to that which is available to C or C++ programmers using the native ODBC (Open Database Connectivity) interface.

Polyhedra 5.1 supports a wide variety of embedded and server operating systems. Complete availability includes Linux and Embedded Linux (using 2.4 and 2.6 kernels), Sun Solaris 8 and Solaris 9, Microsoft Windows Server 2003, Windows 2000, Windows XP, AIX 4.3.3 and IRIX 6.5. On embedded platforms, support now includes LynxOS 4.0.0, OSE 4.5.x, as well as VxWorks 5.4 and 5.5. Polyhedra also supports a variety of compilers, such as GCC and GNU or the Sun compiler tools.

More on Polyhedra

Polyhedra is a relational (data is organized in tables) database management system in a small, light, high-performance package. It couples the benefits of an SQL database with built-in fault tolerance, data persistence, and event-driven data change notification. Polyhedra is an in-memory database that holds all its data structures in RAM, giving it much higher performance and greater predictability than disk-based systems.

One key feature unique to Polyhedra is the ability for client applications to launch "active" queries. With active queries, the database keeps the client application up-to-date with live data changes returned by the queries. The result is a fully current display of data as it is being generated and stored. The active query feature makes it possible to notify the application developer of data changes in the database (such as alarm events or configuration changes) without having to ask or "poll" the system. The database automatically "pushes" the changes to the client application.

To ensure robustness and high levels of data protection, Polyhedra follows the client-server software architecture model. Applications connect to the database as clients, which are able to safely perform queries and transactions over that connection. This guarantees that the applications accessing the data and the Polyhedra application holding the data are separated and cannot bring each other down.

Polyhedra can be configured as a fault-tolerant system with a "master" and "standby" database. The standby database is kept up-to-date with data changes on the master by direct message-passing from the master to the standby. A client library code automatically handles failover from one server to the other without any need for specific coding by the application developer. It automatically reconnects to the new master database, re-establishes active queries, and gracefully handles queries and transactions that were in progress at the point of failover.

Availability and Demo Downloads

Polyhedra 5.1 is available now from Enea Embedded Technology. Pricing starts at $11,995 for a single development license.
