In this paper, we extend the geographic database (GDB) schema with some special "functional attributes" in order to use data cube stored in a Multidimensional Database (MDB). They support links between above mentioned databases through geographic dimensions always implicitly or explicitly present in MDDB. The main goal of this paper is to propose a solution to answer queries involving data stored in both environments in a transparent way to the user. A query langauge to support the common use of multidimensional and geographic operators is proposed. Finally, the main characteristics of the proposed approach are illustrated by a query example.

Abstract
In this paper, we extend the geographic database (GDB) schema with some special "functional attributes" in order to use data cube stored in a Multidimensional Database (MDB). They support links between above mentioned databases through geographic dimensions always implicitly or explicitly present in MDDB. The main goal of this paper is to propose a solution to answer queries involving data stored in both environments in a transparent way to the user. A query langauge to support the common use of multidimensional and geographic operators is proposed. Finally, the main characteristics of the proposed approach are illustrated by a query example.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
