A graphical query and data mining interface provides visual feedback to a user during the construction of a query that helps the user determine the quality of the query as the query is being built. The graphical query and data mining interface determines relationships in the database from a database relationship document, such as an XML document. These relationships may be between columns, including columns in different tables. The relationship of columns in the database is then graphically displayed to a user. When the user selects a column in the database, a filtered display mechanism displays only those columns or records that satisfy the portion of the query already constructed. In this manner dynamic information is provided to the user as the user builds the query that indicates to the user the quality of the query.

A graphical query interface provides visual feedback to a user during the construction of a query. In a first embodiment, the visual feedback helps the user determine the quality of the query as the query is being built. The relationship of columns in the database is graphically displayed to a user. When the user selects a column in the database, a filtered display mechanism displays only those columns or records that satisfy the portion of the query already constructed. In a second embodiment, the visual feedback eliminates some possible selections in the query tree due to previously-made selections that eliminate the eliminated selections as possibilities. In the second embodiment, the visual feedback mechanism may function according to data values in columns, and may also function according to known relationships between columns themselves.
