Oracle SDO, or
Oracle Spatial, is the spatial extension of Oracle in its
version 7.3. This extension has been renamed to Spatial Cartridge
in the version 8.0 and has been renamed again to Oracle Spatial in
the version 8i.
The classes are based on the relational implementation
of Oracle Spatial available since Oracle 7.3. It contains classes
that facilitate the use of map data (stored in an Oracle database)
in a Rogue Wave® JViews application.
Oracle Spatial allows you to store georeferenced objects
in an Oracle database and to perform spatial queries, such as getting
the list of objects that intersect a specific polygon.
Oracle has written two implementations of Oracle Spatial:

tables, available since Oracle 7.3.
An implementation based on the Object
Relational model, available since Oracle 8i, which also contains the
relational implementation of Oracle Spatial.

in the relational and the object relational model of Oracle Spatial
through two different packages:
The Oracle Spatial Reader and Writer comprises the following
