Data Management Solution for Device, Edge and Gateway

Proven to be the fastest hybrid persistent and in-memory database system for edge and cloud.

eXtremeDB offers more features than any other database management system, giving professional developers reliability, speed and connectivity solutions for current needs and future growth.

IoT Connectivity Solutions

eXtremeDB with Active Replication Fabric™ offers reliable data management for IoT by solving 5 challenges for IoT system developers:


Bidirectional Replication


Intermittent connections




Multi-tier replication (e.g. edge-to-gateway-to-gateway-to-cloud)


Compression to maximize limited bandwidth networks

Features to Maximize Database Reliability

Database system reliability encompasses protection from loss of database availability, safeguards on data integrity, and resistant to database corruption caused by application software defects.


ACID-compliant transactions


Transaction logging


Non-volatile memory support


Advanced debugging and corruption prevention tools


Type-safe API

Exceptionally fast, with unparalleled flexibility

eXtremeDB was designed from the beginning to maximize database speed, flexibility and reliability for professional developers.  Optimize for speed and persistence, while taking advantage of the most cost-effective and physical space-conserving approaches to data storage.


Flexible In-Memory & Persistent Architecture

eXtremeDB combines the strengths of the on-disk and all-in-memory approaches to data management in a single database system. eXtremeDB was originally designed an optimized as an in-memory database system. Learn why this is important.


Native and SQL APIs for C/C++, Java, C#, Python

eXtremeDB provides the developer with multiple application programming interfaces (APIs). Learn more 


Multiple Database Indexes

B-Tree, R-Tree, Patricia Trie, KD-Tree, Trigram and Hash indexes.  Learn more


A Wide Range of Supported Data Types

eXtremeDB supports structures, arrays, vectors and BLOBs for maximum efficiency. Learn more about this and other key features.

Optional modules include:


An ideal data management solution for application development in fields where ultra-fast responsiveness is a must and SQL is the dominant database language.

High Availability

An active-passive distributed database system for systems with demanding “five-nines” reliability (99.999% up-time).  eXtremeDB is proven data management, used in systems that define the term “mission critical.”


An active-active distributed database system that manages databases across multiple hardware nodes, enabling two or more servers to share the workload.

eXtremeDB is database management wherever you need it.  It’s used by innovative industry leaders world-wide in these markets and others.

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.
