Abstract:
Data visualization is one of the big issues of database research.
OLAP as a decision support technology is highly related to the
developments of data visualization area. In this paper we
demonstrate how the Cube Presentation Model (CPM), a novel
presentational model for OLAP screens, can be naturally mapped
on the Table Lens, which is an advanced visualization technique
from the Human-Computer Interaction area, particularly tailored
for cross-tab reports. We consider how the user interacts with an
OLAP screen and based on the particularities of Table Lens, we
propose an automated proactive users support. Finally, we discuss
the necessity and the applicability of advanced visualization
techniques in the presence of recent technological developments.
