DB2 Spatial Extender (cont.)
With DB2 Spatial Extender, you can use a single query to retrieve from DB2 both spatial and standard relational data about the same geographic features. When DB2 Spatial Extender is part of a federated system, you can use a single query to retrieve spatial information about a feature from DB2, plus standard relational data about the same feature from other data sources. For example, you can retrieve information from DB2 Universal Database for iSeries or from Informix Dynamic Server.
