This paper describes the ORACLE implementation of PSQL, a query language that allows spatial search and GIS capabilities on ORACLE databases. Spatial search and spatial joins are supported by variations of R-trees, which are excellent storage and retrieval devices for spatial objects and their relationships in multi-dimensional space. Other excellent features of the PSQL software package are that it requires no modification to the ORACLE databases and interoperates with ORACLE on a direct and interactive connection.
