The developments in DBMSs are quite significant in the last several years. Mainstream DBMSs (Oracle, IBM DB2, Informix, Ingres) have already implemented spatial data types and spatial operators similar to the OpenGIS Consortium Simple Features Specification for SQL. The implementation consists of an SQL extension that supports storage, retrieval, query and update of simple spatial features (points, lines and polygons). Currently the implementations are only 2D, i.e. point, line and polygon are supported. However, in most DBMSs 3D coordinates can be used to represent 2D features in 3D (3D points, 3D lines and 3D polygons). Specifications for complex features (topology) as well as for 3D geometry objects are currently being developed by the O...
