Topology Built from Spatial Geometries

Question

Hello, I am trying creating topology from example:
CREATE TABLE city_streets6_geom ( -- City streets/roads
name VARCHAR2(30) PRIMARY KEY,
geometry SDO_GEOMETRY);
CREATE TABLE traffic_signs6_geom ( -- Traffic signs

geometry SDO_GEOMETRY);

DIMINFO,
SRID)

SDO_DIM_ELEMENT('X', 0, 65, 0.005),

What should i do with this problem?
Thanks

Answer 1

thank you for reply.
i can try to network topology.
but i have more than one layer. for example lands, waters, etc.
actually i need left face, right face, start node, end node etc. (topology info) information for my application.
my question is on going...
thanks for interest again
