Spatio-Temporal Queries for Moving Objects Data Warehousing

Abstract

In the last decade, Moving Object Databases (MODs) have attracted a lot of attention from researchers. Several research works were conducted to extend traditional database techniques to accommodate the new requirements imposed by the continuous change in location information of moving objects. Managing, querying, storing, and mining moving objects were the key research directions. This extensive interest in moving objects is a natural consequence of the recent ubiquitous location-aware devices, such as PDAs, mobile phones, etc., as well as the variety of information that can be extracted from such new databases. In this paper we propose a Spatio-Temporal data warehousing (STDW) for efficiently querying location information of moving objects. The proposed schema introduces new measures like direction majority and other direction-based measures that enhance the decision making based on location information.
