eXtremeDB/rt allows embedded and real-time system developers to specify deadlines for database transactions. It is uniquely suitable for real-time systems that must respond within well-defined time constraints. For example, advanced driver assistance systems (ADAS) need to ingest data from multiple sources (sensor data fusion): LIDAR, RADAR, cameras, GPS and maps to name a few, and be able to act on that data within milliseconds to maneuver the vehicle. Guaranteeing that the system can respond within 50 milliseconds for example, requires a real-time database system.

Like conventional eXtremeDB, eXtremeDB/rt is an embedded database management system that provides services for the storage, retrieval and manipulation of data. The differences lay in the temporal requirements of the managed data, transaction scheduling policies, timing constraints on transactions, and in performance goals. It is an ACID-compliant DBMS, maintaining a databases’ internal consistency, and preventing contradictory data in the same database. In addition to preserving internal consistency, eXtremeDB/rt ensures that stored data reflects the state of the real world at a moment in time (temporal consistency).
