Topology. Topology is a property belonging to a spatial object and that property remains unaltered even when the object deforms. An example is a road network. The two nodes in the network thus remain connected even if the path between the nodes is changed by road construction. In order to represent the topology, the basic primitives such as networks (i.e., graphs) and partitions are provided. Additional primitives can be added on lines of the Worboy model, This system support representation for stored data.
