McObject’s eXtremeDB In-Memory Database Hits the Highway In NEXIQ Technologies’ Vehicle Telematics System
Within the NEXIQ PRISM Telematics On-Board Unit (OBU), eXtremeDB runs on Wind River Systems’ VxWorks real-time operating system, providing real-time storage and retrieval of geographical information systems (GIS) data. eXtremeDB also manages critical device configuration information.
NEXIQ turned to eXtremeDB when new system features required a structured way to save, retrieve, and search hierarchical data across power cycles, Engineering Manager Sunil Reddy said.
"Our alternative to using a commercial database was writing our own flat-file structure and a set of software classes to manage the file," Reddy said. "Incorporating McObject's proven eXtremeDB provides a much more expandable solution. In the future, we can easily add new storage for additional applications with varying data needs, without creating new file structures and classes each time.”
eXtremeDB’s role in NEXIQ’s eTechnician illustrates how McObject’s commercial, off-the-shelf (COTS) database supports both the new features that are needed now, as well as capabilities that are sure to be added down the road. Incorporating eXtremeDB rather than a ‘homegrown’ data management solution addresses present as well as future challenges cost-effectively,” McObject CEO and Co-founder Steve Graves said.
eTechnician is a wireless Web-based system that enables remote monitoring and diagnosis of on-the-road trucks and fleet vehicles. From the comfort of the home office or service bay, a manager can access and control an entire fleet's electronically controlled components, including engines, transmissions, and braking systems. eTechnician's scalable ASP infrastructure also allows the user to start with base-level services, then add features, including 3rd party applications, as your savings accumulate.
The mobile system of eTechnician is a Telematics On-Board Unit called PRISM. PRISM is an expandable custom hardware platform designed and manufactured to reside on a wide variety of vehicles with different component specifications and needs. PRISM is capable of running multiple applications while acting as a vehicle data gateway for others, and is charged with three main tasks: vehicle data processing, wireless communication, and interfacing with the vehicle.
Since eXtremeDB’s launch in 2002, manufacturers have embedded McObject’s in-memory embedded database system in set-top boxes, mobile phones, military/aerospace equipment, telecom and netcom gear, MP3 players, industrial control and in many other devices and real-time software applications.
With eXtremeDB, McObject offers a highly portable database management system that meets the unique performance requirements and resource constraints of intelligent, connected devices. eXtremeDB provides critical data management features—including transactions, concurrent access, High Availability and a high-level data definition language—while maintaining a tiny code footprint (as little as 50K). As an in-memory database system (IMDS), eXtremeDB delivers the real-time responsiveness demanded in many device categories that cannot tolerate the response latency of on-disk database systems.
eXtremeDB also provides sophisticated development capabilities, such as support for complex data and varied query methods, a powerful debugging environment including a self-diagnostic API that catches a wide range of common programming errors before they slip into runtime code, and optional XML and SQL interfaces.
