McObject Announces Immediate Availability of eXtremeDB/rt for DDC-I’s Deos Real-Time Operating System

eXtremeDB/rt is the first COTS deterministic real-time database system for mission- and safety-critical embedded systems.


September 30, 2021, Seattle: McObject® announces the availability of eXtremeDB/rt for DDC-I’s Deos™ real-time operating system, a safety-critical embedded RTOS that employs patented cache partitioning, memory pools, and safe scheduling to deliver higher CPU utilization than any other certifiable safety-critical COTS RTOS on multi-core processors.

eXtremeDB/rt was originally conceived, designed and implemented as an in-memory embedded database system for embedded systems. In addition to running within the resource-constrained environment of an embedded system, a hard real-time DBMS must operate within the confines of a stringent deadline.  eXtremeDB/rt is a true hard real-time database management system that extends normal database transaction management by incorporating time-cognizance.

A real-time database system must support two outcomes for transactions: 

  • Committed on time (met the deadline)
  • Not committed but aborted on time (missed the deadline)

In a real-time database system, transactions must not be late.  Therefore, a true real-time database system must enforce transaction deadlines.

eXtremeDB/rt will be of particular interest to developers of Human-Machine Interface (HMI) systems, advanced driver assistance systems, aerospace and defense, industrial control/robotics, and medical devices/systems. Its small footprint and frugal use of memory and CPU make it uniquely qualified for these applications.  

“eXtremeDB/rt provides an excellent option for developers of resource-constrained, mission-critical embedded systems who require a compact, real-time embedded database,” said Greg Rose, vice president of marketing and product management at DDC-I. “We look forward to working with McObject to offer eXtremeDB/rt to embedded developers utilizing our Deos real-time operating system.”

Find eXtremeDB in millions of embedded systems, in deployments ranging from satellite systems to locomotive control, world-wide.
