Several tables make up a complete topological data structure, as discussed in the next section. Various tables derived from topological database information . The power behind topology is the set of integrated topology tables containing the data structure information used in feature definition and in determining spatial relationships. The tables are created automatically when topology is applied to the data. As noted, nodes and chains define line and polygon features, and are the important data structure components for topology.
Topology traces features by finding nodes, chains, and polygons as needed.
The Chain Topology table presents each chain and its start and end nodes. Then the Node Topology table lists the chains that connect to each node. Study and verify the tables. Find each connection. These tables work together to define spatial relationships.
