For hard real-time systems

A fast, reliable and cost-effective embedded database system for embedded systems and intelligent devices.

Embedded systems manage growing volumes of complex data. Commercial pressures impose a shorter development cycle, with demands for reduced costs and more speed, features and reliability.

McObject created the eXtremeDB Database System and related product family to meet these challenges. Thousands of embedded software developers have worked with eXtremeDB and the database plays a key role in millions of deployed applications, ranging from set-top boxes to networking gear, mission critical avionics, industrial controllers, medical technology and more.

Reduce development time

Rich development tools.
A wide range of supported data and query types adds to developer efficiency. The eXtremeDB native C/C++ API is highly intuitive, for quick learning, and lends itself to readable and maintainable code.

Multiple database interfaces.
eXtremeDB provides more application programming interfaces (APIs). For the fastest performance, use eXtremeDB’s native C/C++ API. For standards support, choose the JDBC and ODBC-compliant eXtremeSQL. eXtremeDB also offers native Java, Python and RESTful APIs, and LUA for SQL Stored Procedures.  C# can be used with the ODBC .NET Managed Provider.

More tools.
Comprehensive target-side debugging capabilities, host-side diagnostic tools, optimized data layouts, integrated small footprint embedded web-server, and dozens of supported toolchains all ensure maximum flexibility for developers and minimize time-to-market.

Code quality enforced.
A type-safe API for C/C++ and run-time verification for all languages mean data typing and usage errors are caught early. Result: higher quality code, shorter development cycles and dramatically fewer costly errors.

Flexible persistence.
Fine-tune data persistence with eXtremeDB Transaction Logging. Store all or part of your data on disk (or SSD). eXtremeDB also supports non-volatile RAM (NV-RAM) for storage.

Source code available.
Provides the ultimate transparency for developers using eXtremeDB. Use it for porting, learning, or to add a needed function.  Contact us to learn more.

A proven solution.
Compared to self-developed (‘homegrown’) data management, eXtremeDB offers a proven solution that slashes months from development, QA and ongoing support.

A DBMS that is optimized to be an in-memory database can be hundreds of times faster than an in-memory database that merely substitutes RAM for persistent media as the storage medium.

Reduce production costs

Reduced manufacturing costs.
Small code size and minimal overhead (as little as 15%) means less RAM is required; eXtremeDB’s streamlined design permits a lower cost CPU. Component costs drop, giving your device a cost advantage.

Your competitive edge.
Use the extra CPU speed to offer a snappier user experience than your competition, and use the extra memory to manage more data at the same cost as competing products.

Re-use your code.
Leverage your development investment: as one of the most portable database systems, eXtremeDB deploys easily on new platforms, and even runs without an operating system in “bare bones boards” deployments.

eXtremeDB can pay for itself because the type-safe API catches errors early in development and it uses RAM so efficiently.  Contact one of our engineers to discuss your project.

Add the flexibility for growth and adaptation

Platform independent.
eXtremeDB runs predictably on dozens of hardware architectures and operating systems.  Learn more.

Edge to cloud data management.
Fast, flexible eXtremeDB is data management wherever you need it, and can be deployed as an embedded database system, and/or as a client/server database system.

What other features make eXtremeDB the best choice for developers?

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

eXtremeDB database system is used by industry leaders in over 30,000,000 deployments worldwide.

No other database management system offers more to developers.

Hybrid data storage

Based on an IMDS tiny footprint eXtremeDB databases can be all-in-memory, all-persistent, or have a mix of in-memory tables and persistent tables with a simple database schema.

Active Replication Fabric

Active Replication Fabric™ offers reliable IoT database management by solving 5 key challenges for developers.

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.


Pipelining combines built-in vector-based statistical functions into assembly lines of processing for time series data, with the output of one function becoming input for the next.

Row & columnar flexibility 

eXtremeDB offers columnar data layout for time series data. Combine row-based and column-based layouts in order to best leverage the CPU cache speed. Learn how.

Embedded and/or client server

Fast, flexible eXtremeDB is data management wherever you need it, and can be deployed as an embedded database system, and/or as a client/server database system.
