A definition manager independently defines a plurality of dimensional members of a data source. An operation manager receives user input selecting a set of dimensional members of interest and at least one operator to manipulate the selected set of members based on the selected at least one operator. The set of dimensional members of interest comprise a first dimensional member of interest having a given dimension and a given level in a hierarchy of the given dimension and a second dimensional member of interest having a different dimension from the given dimension or a different level in the hierarchy from the given level in the hierarchy. A display manager places the manipulated set of dimensional members in a report so that the manipulated set of dimensional members are displayed adjacently based on the operator to facilitate comparative analysis.
