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. |
