McObject Embedded Database Reference Applications
The Boeing Company
The Boeing Company, maker of the world-leading AH-64D Apache Longbow multi-role combat helicopter, is using the XML-enabled, High Availability version of the eXtremeDB in-memory database system (IMDS) as part of research and development on the vehicle’s critical real-time on-board systems.

Within the Apache Longbow, the eXtremeDB real-time database will manage secure, digitized battlefield data. eXtremeDB’s XML interface will facilitate communications, both internally and between the attack helicopter and external (ground and air) systems. Embedded software including eXtremeDB will run on airborne PowerPC processors and a commercial real-time operating system (RTOS). The program is being developed by The Boeing Company’s Phantom Works organization in Mesa, Arizona.

The eXtremeDB High Availability Edition provides the highest degree of reliability for the Apache’s mission-critical systems. eXtremeDB’s streamlined design and in-memory deployment deliver the near-zero-latency responsiveness required for advanced systems like a combat helicopter.

The Apache Longbow helicopter first rolled off the Boeing assembly lines 20
years ago. Eleven nations now rely on Apaches to meet their defense needs, and a
number of potential customers are evaluating the system.
Today’s technologically advanced Apache Longbow is the world's only
fourth-generation attack helicopter and the only combat helicopter in service
with the ability to rapidly detect, classify, prioritize and engage stationary
or moving enemy targets at standoff ranges in nearly all weather environments.
Current enhancements to the vehicle will allow the Apache Longbow to fulfill its
key role in the digital army of the future for decades to come.
