Abstract
The invention includes a computer readable medium with executable instructions to receive a query based on nested semantic abstractions for corresponding data sources. Data source specific queries are constructed based on the query by executing the query against the nested semantic abstractions. Each data source specific query is associated with an underlying data source described by a nested semantic abstraction. The data source specific queries are executed to produce results and the results are returned.
