We also focus exclusively on spatial feature of Oracle Spatial and Graph in this book. Oracle Spatial mainly consists of the following: A schema (MDSYS derived from Multi-Dimensional System) that defines the storage, syntax, and semantics of the supported geometric (both vector and raster) data typesA spatial indexing mechanism for faster querying and retrievalOperators, functions, and procedures for performing spatial analysis and query operationsA persistent topology data model for working with data about nodes, edges, and faces in a topologyA network data model for modeling and working with spatial networksA GeoRaster data type and associated functions that let you store, index, query, analyze, and deliver raster data The spatial component of a real-world feature is the geometric representation of its shape in some coordinate space (either in 2D or 3D), and in vector space, this is referred to as its geometry.

This is the only table in the schema without any geometry information. Each road in turn maps to a set of road segments that are stored in the ROAD_CLINES table. This table is used to store the geometric representation of center lines of road segments. This table also stores information about address ranges on these road segments. Road segments typically have different address ranges on the left side of the road and on the right side of the road. Each road segment also has a parent ROAD_ID associated with it from the ROADS table.
