Abstract
Spatio-temporal databases are the result of the aggregation of time and space into a single unified system. Such systems are able to process, manage and analyse spatio-temporal data. Spatio-temporal Database Management Systems (STDBMS) are able to process, manage and analyse spatio-temporal data. Currently, Moving Object Database (MOD) applications are being developed in an unordered fashion. Database Management System (DBMS) technology provides a potential foundation upon which to develop these applications, however, DBMS's are currently not tuned for this purpose. The reason is that there is a critical set of capabilities that are needed by moving objects database applications and are lacking in existing DBMS's. Existing DBMS's are not well equipped to handle continuously changing data.The key problem is how to model the location of moving objects and enable DBMS to predict the future location of a moving object by using efficient index and query manners.Generally, a query in MOD applications involves spatial objects (e.g. points, lines, regions, polygons) and temporal constraints.
This paper presents behavioral aspect of the spatio-temporal databases for managing and querying moving objects.Our objective is to develop a framework that provides spatio-temporal functionality to Oracle10g Object-Relational Database Management System (ORDBMS) to support modeling and querying moving objects. The results of the evaluation are demonstrated in this paper.
