non-graphical sub-feature

Hi,

can somebody please shed some light on this... (taken from )

Oracle Spatial Non-Graphical Sub-Feature Support
It is now possible to create sub-features of type non-graphical using Oracle foreign key constraints between a graphical main table and a non-graphical linked table

 

Can this be used even without Oracle Spatial? What's the idea and how can I use it?


TIA,

 Holger
