Linux Database Management System

Proven the fastest hybrid persistent and in-memory Linux database management system for edge and cloud.

What makes eXtremeDB different?

Platform independent eXtremeDB has been a Linux database management system from the beginning.  Created to be a powerful tool for the professional developer, eXtremeDB offers the features you’ll find in other database management systems, and some that you won’t, (like those below), to give your next project a competitive edge.

An In-Memory and Persistent DBMS

eXtremeDB was originally designed and optimized to be an in-memory database system (IMDS) and this distinction allows for improved performance.  Learn why here.

The eXtremeDB hybrid database system offers the strengths of the on-disk and all-in-memory approaches to data management in a single database system.

Active Replication Fabric

eXtremeDB Active Replication Fabric stages data during network malfunctions or outages, then sends the relevant historical data to the network as soon as the connection is reestablished.

Ideal for:

    • mobile IoT systems that move in/out of coverage
    • battery operated field devices’ need to conserve power

Pipelined, vector-based analytics for time series data

Pipelining is the programming technique in eXtremeDB that accelerates processing by combining the database system’s vector-based statistical functions into assembly lines of processing, with the output of one function becoming input for the next.  Watch a quick video about pipelining.

Network & Telecom

Network gear developers build on proven eXtremeDB speed and reliability, combined in-memory and persistent data layouts, optimized access methods and unmatched flexibility.

Consumer Electronics

JVC, DirecTV, GoPro and others all discovered that eXtremeDB’s small code size, portable data format and efficient use of compute & storage can reduce component cost while also supporting data-hungry new features.

Industrial Systems

eXtremeDB’s sophisticated event notification systems, time series data processing and high availability have powered its wide-spread adoption in SCADA, fleet management, smart building automation and other verticals.

Aerospace & Defense

Northrop Grumman, Lockheed Martin, British Aerospace, EADS and others depend on eXtremeDB’s reliability, unmatched performance and broad platform support.


eXtremeDB optimization technology can dramatically boost utilities’ power generation yields. Distribution networks can become self-healing and bi-directional, enabling end-users to contribute power back to the grid.


eXtremeDB’s unique hybrid row- and columnar-layout (OLTP and time series) couples with pipelined functions for statistical analysis and scalable distributed database architecture power record-setting STAC-M3 benchmark results.

Hard Real-time Systems

eXtremeDB/rt is the first and only deterministic embedded DBMS for mission- and safety-critical hard real-time applications. It is built to satisfy strict requirements for timely execution of avionics and aircraft navigation systems, driver assistance systems, critical medical equipment and similar systems’ data management.

Big Data & Analytics

Columnar and row-oriented storage, a SQL engine infused with advanced analytics, and a scalable distributed architecture deliver speed and reliability to complex data-driven applications.
