Find out the features of the Polyhedra family of relational DBMS products, and how to use them!

This web site contains a lot of information about the Polyhedra family of relational DBMS products, including descriptions of the special features, and a number of technical notes. A good place to start, though, is to have a quick look at a webcast giving a 5-minute demo of Polyhedra. Then, use the links in the left-hand tool bar to find out more!

The reference manuals are also online, but are only accessible to those who have joined the Polyhedra Users' Forum - see below.

Polyhedra Support

Customers who have purchased Polyhedra developer licenses for particular platform(s) can take out annual support licenses, which allows them to contact the Polyhedra support desk to report bugs and problems; it also allows them to obtain new releases as they become available for their licensed platforms, including upgrades. People who are using the free Polyhedra Lite product can purchase annual support contracts if they wish, or can use the support forum - see below.

Polyhedra Users Forum

There is a special polyhedra-dbms Google Group that has been set up to act as a self-help user forum; all Polyhedra users are welcome to join that group and use it to answer questions. Of course, it is good netiquette to help fellow users by answering questions posted there!

Latest news

  • Polyhedra 9.0 released: faster, more flexible and more scaleable!

Polyhedra 9.0 introduces substantial performance improvements, a way of allowing a database to keep a live cache of information retrieved from other Polyhedra databases, and an ADO.NET data provider that allows the .NET programmer to take advantage of Polyhedra-specific features such as active queries. For more details, click here.

  • Using Enea Element to control Polyhedra fault tolerance
If you are using Enea's Element product to monitor and control complex embedded systems that need high availability, it makes sense to control Polyhedra via Element as well. We have just created a new section on using Polyhedra with Element, and the first topic covered is an Element 'shim' that acts as an arbitrator for Polyhedra. We have also published a one-minute video showing this shim in action! 
  • Polyhedra on the Pi2!
The Raspberry Pi Foundation has released the Pi 2 board, which uses a faster processor and has double the about of RAM. To get full advantage of this processor applications will have to be recompiled using the ARM11 instruction set - but existing code will work on it, and Polyhedra will run 4-8 times faster! We've posted a comment about the performance improvement over on the Raspberry Pi forum.
