Abstract: A data driven natural interface is provided for automated relational queries. Multiple datasets are displayed in an easily selectable manner on a surface. Upon detecting selection and movement of a dataset to another surface, the moved data is presented on the other surface. Upon detecting selection and movement of another dataset to the other surface, a join path between the moved datasets is computed, the datasets joined, and results displayed on the other surface. The system continues to join newly selected data with existing data as new datasets are moved to the other surface allowing query results to take shape before the user's eyes, without a need to test or execute the query.
