ABSTRACT:
A computer readable storage medium comprises executable instructions to receive a query referencing a set of members of an OLAP hierarchy. The query is parsed into a syntax tree. Changes to the OLAP hierarchy metadata are received. The syntax tree is refined in response to the changes. The query is evaluated to return results that are independent of the changes to the OLAP hierarchy metadata.
