Abstract
Data warehouse is organized as collection of
multidimensional cube, which represents data in the form
of data values, called measures, associated with multiple
dimensions and their multiple classification levels. In
multidimensional cube, object oriented approach may be
used for structuring the data. The focus of the paper is on
operators defined for the object oriented model, required
for formatting the query and results. In this paper object
oriented multidimensional data model is defined for
description of data. Seven operators for the object oriented
model are introduced: intersection, difference, symmetric
difference, restriction, union, join, projection. This paper
extends the work of [7] which includes the four operators’:
restriction, union, join and projection. For every operator
input, output, symbol and mathematical representation of
the operators are defined.
