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

Row & Columnar Flexibility for Time Series Data

Time series data management systems frequently require large volumes of information to be available continuously. eXtremeDB excels in this capability.

Embedded and Client Server

Fast, flexible eXtremeDB is Linux database management wherever you need it.  eXtremeDB runs on device, gateway and server, eliminating the need to learn different DBMS and leverages staff skills. Devices and servers communicate flawlessly.  Learn more.

A Hard Real-time Option

eXtremeDB/rt is the first and only deterministic embedded database management system for mission- and safety-critical hard real-time applications.

Use eXtremeDB in these markets and others.

Network Infrastructure

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

Embedded Applications

From inception, eXtremeDB’s resilient and optimized storage capabilities uniquely qualified it to fuel database management for safety-critical and resource-constrained embedded applications.

Internet of Things

eXtremeDB’s Active Replication Fabric™ creates a data management foundation for the IoT ecosystem that seamlessly integrates edge and cloud applications’ storage and ensuring data safety all around.e

Big Data & Analytics

Offers columnar storage for time-series data, as well as traditional row-oriented storage for OLTP, an SQL engine infused with advanced analytics, and a scalable distributed architecture deliver speed and reliability to complex data-driven applications.

Mission- and safety-critical applications

eXtremeDB/rt is the first and only deterministic embedded database management system 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. The groundbreaking design of eXtremeDB/rt preserves the external and internal consistency of data by enforcing transaction deadlines and the ACID properties.

Created to be a powerful tool for the professional developer.
