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.
