How to create a topology from topology data?
The main steps for working with a topology built from topology data are as follows: Create the topology, using the SDO_TOPO.CREATE_TOPOLOGY procedure. This causes the _EDGE$, _NODE$, _FACE$, and _HISTORY$ tables to be created.
How to build a topology from spatial geometries?
If you will build the topology from Spatial geometries that will become topology features, follow the steps in Section 1.1.2, “Using a Topology Built from Spatial Geometries”. You can use the topology data model PL/SQL and Java APIs to update the topology (for example, to change the data about an edge, node, or face).
How to update the topology data model in Java?
You can use the topology data model PL/SQL and Java APIs to update the topology (for example, to change the data about an edge, node, or face). The PL/SQL API for most editing operations is the SDO_TOPO_MAP package, which is documented in Chapter 4. The Java API is described in Section 1.8.2.
Which is the API for editing topology data?
The PL/SQL API for most editing operations is the SDO_TOPO_MAP package, which is documented in Chapter 4. The Java API is described in Section 1.8.2. The main steps for working with a topology built from topology data are as follows:
How is the topology table used in routing?
The topology table is a database of possible routes. It provides the information that is used to select the best possible route, which is copied into the routing table. The best metric along all possible paths to the remote network is called the feasible distance (FD).
What does dual do in the topology table?
If the successor route goes away, DUAL will search the topology table for a backup route. The topology table is where EIGRP stores the information for up to six alternate routes to a particular network. The backup routes are called feasible successors.
