Enea, a specialist in software platforms for communication-driven products, has announced the release of Polyhedra Lite. This new offering is a freeware version of the company’s established Polyhedra in-memory database system, designed specifically to provide embedded systems developers with a fast and flexible relational database for personal or in-house projects.
While the full version of Polyhedra is often utilized in mission-critical 3G and 4G infrastructure where fault tolerance is essential, Polyhedra Lite targets applications where high availability is not the primary requirement. The software operates as a relational client-server database management system and is available for Windows on x86 architectures, as well as Linux on x86 and Raspberry Pi platforms.
Technically, Polyhedra Lite maintains full ACID compliance to ensure data reliability. Developers can access the system via standard ODBC and JDBC interfaces using SQL. To enhance performance and maintain data integrity, the system allows users to attach business logic directly to the database using the CL trigger language. Additionally, the system features active queries, a mechanism that enables applications to detect database changes instantly without the overhead of constant polling.
The software supports distributed architectures, allowing client applications to reside either on the same machine as the database or on a separate network node. While the software itself is available as freeware, Enea provides optional support services via an annual fee based on the total number of installations.
With four decades of experience in real-time operating systems and high-availability middleware, Enea developed this version to streamline development cycles for engineers working across various sectors, including telecom, medtech, and automotive.
