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.
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.
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! In addition, all members of the group will be able to download the Polyhedra reference manuals, and - provided they agree to abide by the Polyhedra Lite license agreement - some drivers for use with Polyhedra Lite.
This site is maintained by Enea staff, and we try to keep it accurate. However, as described here, errors will creep in; if in doubt, check with the reference manuals, all of which are available in PDF form for offline reading (provided you have registered as a member of the forum). If you spot an error on this site and you have a support contract, you can report it via the Polyhedra helpdesk; if not, please report it via an email to firstname.lastname@example.org. (Please do not send support questions to the webmaster!)
Polyhedra webmaster will post something to the Twitter account @PolyhedraDBMS
The how-to guide 'inspecting the schema of a Polyhedra database' now has example output from a new version of a CL-coded schema inspection tool, along with a copy of that tool. As well as producing an HTML file describing the schema in detail, the tool can also
