Database for Aerospace & Defense Systems

Military and aerospace systems manage growing volumes of complex data, to perform tasks that define the term “mission critical.”

eXtremeDB and eXtremeDB/rt for Aerospace and Defense.

Whether your system requires deterministic, hard real-time performance guarantees or unparalleled features, McObject’s eXtremeDB embedded database system delivers with a proven track record for aerospace and defense embedded software. eXtremeDB maximizes uptime and slashes time-to-market, compared to other off-the-shelf (COTS) database systems or to custom data management code.  eXtremeDB/rt is the only COTS real-time database system for mission-critical systems.

Combat Jet Avionics

Target applications include:

  • Battlefield Management
  • Missile Intercept
  • Pilot Assistance
  • Secure Communications
  • Navigation
  • Simulation

In eXtremeDB, application developers gain a database solution product family that includes:

  • The core eXtremeDB product architecture with ultra-fast performance and a tiny footprint
  • High Availability for proven fault-tolerance
  • Cluster for cooperative distributed database applications
  • 64-bit support and optional multi-version concurrency control (MVCC) transaction management, for high scalability (proven in 1+ terabyte in-memory database deployments, and 10s of terabyte persistent database deployments)

Command and Control

Features to develop highly optimized embedded software:

  • More application programming interfaces (APIs): native, navigational C/C++ API for fastest operation, standard SQL ODBC & JDBC, Java Native Interface (JNI), and Python. C# can be used with the ODBC .NET Managed Provider.
  • Highest possible code quality via C/C++ self-diagnostic API’s type safety; no dynamic memory allocation; and sophisticated debugging and error-handling
  • Specialized data indexes, including R-Trees for mapping/navigation and Patricia tries for communications
  • Source code available

eXtremeDB has the broadest support for OSs and RTOSs, including Wind River Systems’ specialized VxWorks, VxWorks 653 for avionics and Green Hills Integrity on virtually any 32- or 64-bit processor. eXtremeDB is so free of dependencies, it can run without an OS (“bare bones boards”), and without support from the C run-time library.

Fault-Tolerant Memory Management for Mission Critical Embedded Systems
Memory management is a key programming concept for eliminating the possibility of bottlenecks and failure in embedded software. This Webinar presents memory management techniques to optimize code, focusing on the beneficial role of highly efficient custom allocators.  The solutions presented retain the power and flexibility of dynamic memory management while mitigating common risks, and improving efficiency and performance.

Embedded Databases: Building In Always On High Availability
This Web seminar highlights the issue of operational continuity: how can a database system survive the failure of the software or hardware environment in which it operates? How can it deliver high performance as well as fault-tolerance? Led by McObject CEO Steve Graves, this Webinar presents development solutions that address the “always on” needs of fault-tolerant systems, while taming these applications’ growing data complexity.
