34 DB2 Cube Views: A Primer
that a change made in a data modeling tool will affect an OLAP object in DB2
Cube Views using cross-tool impact analysis reporting. This reduces errors that
might otherwise arise due to false assumptions about data lineage or the
possible impacts of changes in design.
Data model enrichment
Let’s say you modeled your basic star schema in a data modeling tool, but you
did not model the dimensional hierarchies or derived attributes there. Let’s say
further that after you imported this metadata into DB2 Cube Views, you added
the dimensional hierarchy and derived attribute information using the OLAP
Center. If your data modeling tool has a two-way metadata bridge, then you can
send the enhanced model back to the data ...
