Towards Sensor Database Systems doc

... Conclusion We believe that sensor database systems are a promising new field for database research. We described a data model and long-running query semantics for sensor database systems where stored ... Sensor Data A sensor database involves stored data and sensor data. Stored data include the set of sensors that participate in the sensor database together with...

We address both of these ... consistency) in order to achieve scalable distributed database systems (e.g. many so-called “NoSQL” systems) . Deterministic database systems that use active replication only need...
