SW9-90-003 ABSTRACT The invention relates to a method of querying a data base in a computer system containing input means, processor means, graphical display means and storage means. The data base contains objects relating to a specified and limited domain of knowledge. A query is composed by direct manipulation of graphical representations of said objects on a screen. The graphical representations are stored in memory, and each such graphical representation has a unique link to an entity in a conceptual schema, said schema containing a first set of records of data (entities) which are language independent representations of the objects in the data base. The invention also relates to a query composition apparatus, suitable for retrieval of information from data bases. It comprises a data processor, a display unit with a manipulation area for manipulating graphical representations of data items stored in the data base, and a stored formalized description of the data base, said description being kept in storage and containing data records representing the items in the data base.
