Cascaded ECOLAP operations

Marcin Gorawski, Marcin Bugdoł

Abstract


The paper proposes the new definitions of Expanded Cascaded OLAP (ECOLAP) operations by using the relation algebra. The operations have been defined for the extended cascaded star schema in spatial data warehouse SDW basing on the existing definitions of the COLAP operations for the cascaded star schema. Moreover, they support extensions presented in the new logical model.

Keywords
