Using Oracle Extensibility Framework for Supporting Temporal and Spatio-Temporal Applications

Databases such as Oracle, IBM, SQLServer are increasing their support for temporal and spatio- temporal data with every release. In this paper, we describe how Oracle users can extend the existing functionality in Oracle and ground their research by using Oracle´s extensibility. To illustrate its applicability to temporal data, we present how a Map21 (M.A. Nascimento and M.H. Dunham, 1999) based index can be implemented using this framework.. Oracle uses the same extensibility framework to implement R-trees and rules manager. We describe enhancements to Oracle´ R-trees for spatio-temporal data, and real-time event processing using Oracle´s rules manager.
