hi, friends,<br>
I've noticed in oracle 11g/10g, they support network data model, which you could find here:Spatial Topology and Network Data Models Developer's Guide:<a href="http://download.oracle.com/docs/cd/E11882_01/appdev.112/e11831/toc.htm">http://download.oracle.com/docs/cd/E11882_01/appdev.112/e11831/toc.htm</a>.
<br>
I wondered are there any related part in PostGIS or 3rh part open source project?<br>
Thanks!<br>
