Consider applications of a database that models information about moving objects and their location. For example, given a database representing the location of taxi-cabs, a typical query may be: retrieve the free cabs that are currently within 1 mile of a customer at 33 N. Michigan Ave.. Military applications utilizing moving objects databases arise in the context of the digital battlefield, and civilian ones arise in transportation systems and in systems that track mobile computers for providing context awareness.
Currently, moving objects database applications are being developed in an ad hoc fashion. Database Management System (DBMS) technology provides a potential foundation upon which to build these applications, however, there is a critical set of needed capabilities that are lacking in existing DBMS's. These include support for continuously changing data, integrated spatial and temporal information, and uncertainty management. The objective of our Databases fOr MovINg Objects (DOMINO) project is to build an envelope containing these capabilities on top of existing DBMS's. In this talk I will describe the problems addressed by the project, and our proposed solutions.
