Abstract
A method and system for accessing information or data from distributed databases is disclosed. Generally, the method includes the steps of receiving an unstructured query from a user, generalizing the query to expand the query, receiving from the user selected terms of the expanded query, searching a directory for database tables and/or attributes matching the selected terms, and generating a pictorial query using database tables suggested as relevant by the search. Thereafter, an SQL query may be generated to retrieve the relevant data from the actual distributed databases.
