Early in development, STM product designers faced a classic "build or buy" decision: should engineers code the software to manage information in this data-intensive system in-house, or integrate a commercial off-the-shelf (COTS) high availability database (http://www.mcobject.com/highavailability.shtml) in their application?
The company went the COTS route, choosing eXtremeDB-HA, and this decision reduced coding and QA cycles by approximately 4 developer-months, STM reports. The company expects further savings by relying on McObject for support and software updates.
Within the TCCIS, eXtremeDB-HA is deployed in the Vehicle Command Control Computer (VCCC). In this core system component, the high availability database coordinates input from on-board systems such as navigation, friend-or-foe identification, fire control, odometer and radio, and provides VCCC applications with real-time access to stored information ranging from tactical data to orders, maps, vehicle electronics (vetronics) output, warnings and failure reports.
eXtremeDB-HA met two early stage requirements: it is available on the VxWorks real-time operating system (RTOS), and runs in both VxWorks' kernel module (DKM) and as a real-time process (RTP). It also met the application's stringent real-time performance requirements.
To provide the reliability critical in battle-ready systems, STM chose the High Availability edition from McObject's diverse eXtremeDB embedded database (http://www.mcobject.com/extremedbfamily.shtml) product family. This choice provides unmatched reliability by enabling deployment of a master database and multiple synchronized copies, with automatic failover. eXtremeDB-HA offers a strong track record in military/aerospace, telecom, networking and other fault-tolerant applications.
STM also chose McObject's hybrid database technology, eXtremeDB Fusion. With this product, the developer specifies, with a simple database schema notation, which record types are to be stored on permanent media and which will be managed in memory. This lets STM tailor the storage to achieve desired persistence and performance for each task.
"During our lengthy evaluation, McObject responded quickly to every technical question. The support has been excellent. In addition, we were able to arrange for a McObject engineer to come to our premises for training, and the instruction was both professional and very clear," said Mrs. Ozlem Dengizek, STM project manager.
According to Jane's International Defence Review, a prototype of the TCCIS is expected to be completed in October 2009, with delivery of a platform-ready prototype in June 2010. The TCCIS aims to provide all units, from single vehicles to the battalion force level, "with improved situational awareness and a tactical picture of the battlefield," Jane's reported.
McObject's eXtremeDB provides a highly portable database management system that meets the unique performance requirements and resource constraints of embedded systems and intelligent, connected devices. eXtremeDB provides critical data management features---including transactions, concurrent access, and a high-level data definition language---while maintaining a code footprint as small as 50K. It is available as a standard in-memory database (http://www.mcobject.com/extremedbfamily.shtml) system and in editions offering high availability, hybrid in-memory/on-disk data storage, kernel mode data management, 64-bit support and more. McObject's Perst(TM) is an open source, object-oriented embedded database, available for Java and .NET, including Java ME and .NET Compact Framework.
