Federal Way, WA and Milford, OH – February 23, 2022 – Industry partners McObject® and Siemens Embedded today announced the availability of McObject’s revolutionary eXtremeDB®/rt database management system (DBMS) for Nucleus™ RTOS-based hard real-time embedded systems.

eXtremeDB/rt is the first commercial-off-the-shelf (COTS) embedded database system to enforce database transaction deadlines, making it uniquely suitable for embedded systems with hard real-time constraints. As an ACID-compliant DBMS, eXtremeDB/rt guarantees internal consistency, but with real-time features also guarantees external consistency when transactions complete within their deadline. With two real-time transaction algorithm implementations, eXtremeDB/rt can be adapted to most any execution pattern, including periodic and aperiodic transactions.

Available since 1993, the Nucleus RTOS from Siemens Embedded has been widely adopted for medical, industrial, consumer, aerospace, and Internet of things (IoT) systems. Nucleus combines a small footprint and lightweight process model with support for SMP, power management, graphics and safety certification.

“Real-time embedded systems are growing increasingly complex, often requiring sophisticated sensor data fusion, which implies centralized management of data ingested from multiple sources. Before eXtremeDB/rt, developers either had to invent their own solution for database transaction deadline management or integrate a non-real-time embedded database and hope it would be good enough.” said Chris Mureen, McObject Chief Operating Officer. 

“McObject’s eXtremeDB/rt allows Nucleus customers to have a truly embedded database solution that allows them to meet the determinism they require in a commercial-off-the-shelf solution.”  said Jeff Hancock, Siemens Embedded Senior Product Manager.eXtremeDB/rt helps Nucleus customers manage ever-growing data requirements.”
