Part I Topology Data Model

This part covers the topology data model feature of Oracle Spatial.

This document has two main parts:

• Part I provides conceptual, usage, and reference information about the Topology Data Model feature of Oracle Spatial.

• Network Data Model provides conceptual, usage, and reference information about the Network Data Model feature of Oracle Spatial.

Part I contains the following chapters:

• Topology Data Model Overview
  The Topology Data Model feature of Oracle Spatial lets you work with data about nodes, edges, and faces in a topology.
• Editing Topologies
  Node and edge data in a topology can be edited. The operations include adding, moving, and removing nodes and edges, and updating the coordinates of an edge.
• SDO_TOPO Package Subprograms
  The MDSYS.SDO_TOPO package contains subprograms (functions and procedures) that constitute part of the PL/SQL application programming interface (API) for the Spatial Topology Data Model feature. This package mainly contains subprograms for creating and managing topologies.
• SDO_TOPO_MAP Package Subprograms
  The MDSYS.SDO_TOPO_MAP package contains subprograms (functions and procedures) that constitute part of the PL/SQL application programming interface (API) for the Spatial Topology Data Model feature.
