+ The GeometryColumns and SpatialRefSys models for the Oracle spatial
+ backend.
+
+ It should be noted that Oracle Spatial does not have database tables
+ named according to the OGC standard, so the closest analogs are used.
+ For example, the `USER_SDO_GEOM_METADATA` is used for the GeometryColumns
+ model and the `SDO_COORD_REF_SYS` is used for the SpatialRefSys model.
