2.3.2 OLAP Scenario


   An end user of a data warehouse engages in an analytic session with a multidimensional or relational database through the OLAP layer. The user navigates cubes and dimensions and selectively launches OLAP queries. At some point, the user decides to drill-down from a consolidated value to lower levels of detail in an OLAP hierarchy, possibly down to the lowest level input value(s) in the hierarchy.

   Leveraging CWM’s inherent ability to preserve data lineage, the user may view the operational detail, which formed the input value(s). The original data sources can be identified from the CWM Warehouse Operation that recorded the production of the input value(s).
