These applications all store, retrieve, update, or query some collection of features that have both nonspatial and spatial attributes.

Examples of nonspatial attributes are name, soil_type, landuse_classification, and part_number.

The benefits provided by the object-relational model include: Oracle Spatial is designed to make spatial data management easier and more natural to users of location-enabled applications and geographic information system (GIS) applications.

Once spatial data is stored in an Oracle database, it can be easily manipulated, retrieved, and related to all other data stored in the database.

consists of coordinate pair values, one vertex pair for each line segment of the polygon.

is an ordered sequence of vertices that are connected by straight line segments or circular arcs.

An Oracle table can contain one or more SDO_GEOMETRY columns.

The object-relational model corresponds to a "SQL with Geometry Types" implementation of spatial feature tables in the Open GIS ODBC/SQL specification for geospatial features.

Oracle Spatial is an integrated set of functions and procedures that enables spatial data to be stored, accessed, and analyzed quickly and efficiently in an Oracle database.

Spatial data represents the essential location characteristics of real or conceptual objects as those objects relate to the real or conceptual space in which they exist.
