Query languages for moving objects

Definition

The term refers to query languages for moving objects databases. Corresponding database systems provide concepts in their data model and data structures in the implementation to represent moving objects, i. e., continuously changing geometries. Two important abstractions are moving point, representing an entity for which only the time‐dependent position is of interest, and moving region, representing an entity for which also the time‐dependent shape and extent are relevant. Examples of moving points are cars, trucks, airplanes, ships, mobile phone users, RFID-equipped goods, and polar bears; examples of moving regions are forest fires, deforestation of the Amazon rain forest, oil spills in the sea, armies, epidemic diseases, and hurricanes.

There are two flavors of such databases. The first, which is called the location managementperspective, represents information about a set of currently moving objects. Basically, one is...

Notes

  1. 1.

    There exists a further query type, persistent query, which is omitted here.

  2. 2.

    In the original literature about FTL, a single class of moving objects is assumed and the FROM clause omitted.

  3. 3.

    It is a bit more complicated in the case of variable size units as for a moving region, for example.
