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.

Processing queries against combinations of data sources

A computer readable storage medium comprises executable instructions to provide a workspace for a user to define an expression with expression components from a graphical palette associated with the workspace. Placeholders are indicated in the workspace for the expression components to be added by the user. The placeholders are associated with a data type. The data type is enforced for each placeholder. A structured visual representation of the expression is provided on the workspace.

Providing structured visualizations of expressions in an expressions editor

A computer implemented method includes receiving a data filter from a first panel of filtering categories. The data filter is applied to a dataset wherein a resulting data subset is created. One or more further data filters is displayed within a nested second panel of filtering categories.
