MySQL has data types that correspond to OpenGIS classes. Some of these types hold single geometry values:
            GEOMETRY
          
            POINT
          
            LINESTRING
          
            POLYGON
          
        GEOMETRY can store geometry values of any
        type. The other single-value types (POINT,
        LINESTRING, and POLYGON)
        restrict their values to a particular geometry type.
      
The other data types hold collections of values:
            MULTIPOINT
          
            MULTILINESTRING
          
            MULTIPOLYGON
          
            GEOMETRYCOLLECTION
          
        GEOMETRYCOLLECTION can store a collection of
        objects of any type. The other collection types
        (MULTIPOINT,
        MULTILINESTRING,
        MULTIPOLYGON, and
        GEOMETRYCOLLECTION) restrict collection
        members to those having a particular geometry type.
