Preface


The Oracle Spatial Data Option User's Guide and Reference provides user and reference information for Spatial Data Option, and extensions to Oracle® Universal Server.


Note :

Spatial Data Option release 7.3.3 introduced two distinct algorithms for building a spatial index: fixed-size tiling and variable-sized tiling. Based on testing and customer feedback, for release 7.3.4, Oracle recommends using only fixed-size tiling on production systems. Variable-sized tiling, while it has theoretical advantages in some situations, is included primarily for experimentation purposes. In the future, Oracle may issue a technical bulletin further refining the usage of variable-sized tiling.
