Spatial databaseA 'spatial database' is a database that is optimized for storing and querying data that represents objects defined in a geometric space. Most spatial databases allow representing simple geometric objects such as points, lines, and polygons. Some spatial databases handle more complex structures such as 3D objects, topological coverages, linear networks, and TINs. While typical databases have developed to manage various numeric and character types of data, such databases require additional functionality to process spatial data types efficiently, and developers have often added ''geometry'' or ''feature'' data types. The Spatial database developed the Spatial database specification (first released in 1997)and sets standards for adding spatial functionality to database systems.The ''SQL/MM Spatial'' ISO/EIC standard is a part of the SQL/MM multimedia standard and extends the Simple Features standard with data types that support circular interpolations.
