Conformance classes SQL
SQL with Geometry Types
Implementation benefits ISO 19125-2 standardizes the names and geometric definitions of the SQL Types for the Geometry class, and names, signatures and geometric definitions of the SQL Functions for Geometry. The implementation of ISO 19125-2 is an extension of SQL and is very simple to use. This extension of SQL is a very effective method of querying a database or performing complex analysis.
Products Two popular implementations of ISO 19125-2 are PostGIS (an extension of PostgreSQL) and Oracle Spatial.
