What makes eXtremeDB different?

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 all the relevant historical data to the network as soon as the connection is reestablished.

Eliminates data loss between device and server.

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.

Telecom & Network

eXtremeDB powers routers, application traffic management, SCADA network fault management and more from industry leaders like F5, ViaSat, Motorola, Sandvine, Hutchinson, TNS and Ribbon that require real-time performance and five 9s high availability.

Internet of Things

eXtremeDB’s Active Replication Fabric™ manages all aspects of IoT data communication: security, low bandwidth, intermittent connections, multi-tier and bi-directional replication, and more.

Aerospace & Defense

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

Financial Systems

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

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 Control

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.
