I gave a talk last month at Embedded World, have a guest blog being published soon, and will be holding webinars in the near future saying essentially what this article says. The media has, so far, been focused on only the "Big Data" challenge posed by the Internet of Things, and that is the entirety of the extent to which database systems have been mentioned in the context of the Internet of Things.
What everyone has been missing is that the "things" both ingest and generate a considerable amount of data, so a database management system appropriate to these devices is needed.
eXtremeDB was launched in 2001 as a new database system for "intelligent, connected devices." Of course, that was long before the phrase Internet of Things entered the scene. eXtremeDB has all the features and capabilities described in this article and has been deployed in approximately 25 million Things, like smart building systems, forklifts and other Industrial Internet of Things, set-top boxes and other consumer electronics, network infrastructure gear, and aerospace and defense systems.
It is great to see at least one analyst (Ovum) and InformationWeek recognize the need.
