Vehicle telematics system gains in-memory embedded database

NEXIQ Technologies, a leading provider of diagnostic and telematics products, solutions and services for the commercial vehicle industry, has integrated McObject's eXtremeDB™ in-memory embedded database system in the on-board telematics device in fleet vehicles as part of NEXIQ’s eTechnician™ Web-based remote monitoring and diagnostics application.

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.
