AetherSystems Distinguished Lecture Series in Mobile and Wireless Systems

Lecture Abstract

Consider applications of a database that models information about moving objects and their location. For example, given a databaserepresenting 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 databasesarise in the context of the digital battlefield,and civilian ones arise in transportation systemsand in systems that track mobile computers forproviding 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 ofneeded capabilities that are lacking in existing DBMS's.These include support for continuously changing data, for integrated spatial and temporal information, and for 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 theproject, and our proposed solutions.
