  What is Networking in Oracle Spatial? I suggest you watch the video below about this article. A spatial network is a collection of connected nodes and edges: Nodes: Points representing intersections, stops, or terminals. Edges: Lines representing roads, pipelines, or pathways. Networking in Oracle Spatial is used for: Finding shortest paths. Analyzing connectivity (e.g., "Can I travel between two points?"). Calculating flow (e.g., traffic, water supply). Key Components of Oracle Spatial Networking Nodes Table: Represents points (e.g., road intersections). Edges Table: Represents connections between nodes (e.g., roads). Network Metadata: Defines the network structure and stores rules. Network Analysis Functions: Built-in functions to analyze the network (e.g., shortest path). Implement Networking 1. Prerequisites Ensure Oracle Spatial and Graph is installed and enabled in your database. Grant necessary privileges to your user: GRANT ALL ON NETWORK_ADMIN TO MY_USER;...

  Creating a Land Parcel Management System with Topology In Oracle Spatial First, what is Topology In Oracle Spatial? In below article, you can find good information about Topology In Oracle spatial https://lidagholizadeh.blogspot.com/2024/05/topology-in-oracle-spatial.html We'll create a topology to manage land parcels in a city. This topology ensures: Parcels (polygons) don’t overlap. Roads (lines) connect without gaps. Landmarks (points) are inside parcels. 1. Prerequisites Ensure Oracle Spatial is installed and your database schema has the required privileges. 2. Create a Topology Workspace A topology workspace acts as a container for managing spatial relationships. BEGIN SDO_TOPO.CREATE_TOPOLOGY( 'CITY_PARCEL_TOPOLOGY' , -- Topology name 'MY_SCHEMA' , -- Schema name 0.001 , -- Tolerance for operations 'GEOMETRY_COLUMN' ); -- Optional geometry column table END ; 3. Define Topology Layers Topology...

 What is Topology in Oracle Spatial? I suggest you watch the video below about this article. Imagine you have a map with streets, parks, and buildings. Topology is like a rulebook that defines relationships between these things: Points (like a park's location) Lines (like roads or rivers) Areas (like a city block or a lake) With topology, we can say: Roads connect at intersections. A park can't overlap a building. A lake must stay inside its boundary. Using topology helps keep your data correct and makes spatial queries faster. For example: Find all parks next to a river. Check if two roads cross. Ensure no two buildings overlap. How to Implement Topology in Oracle Spatial? 1) Create a Topology A topology is like a container for your spatial data. BEGIN SDO_TOPO.CREATE_TOPOLOGY( 'CITY_TOPO' , -- Name of the topology 'USER_SCHEMA' , -- Your database schema 0.005 , -- Tolerance for geometric operations 'GEOMETR...
