CA 2337879

The invention relates to a message for issuing a failure announcement when an attempt is made to gain access to a data base. A filtering condition consisting of a plurality of logically concatenated selection conditions for the specification of output data is imposed on said data base system. A failure weighting is associated with each selection condition. If the filtering condition is not met, the main non-fulfilled selection condition is determined by comparison with the failure weighting.

L'invention concerne un procédé permettant d'afficher un message d'insuccès dans le cas d'une tentative d'accès à une banque de données. Une condition de filtrage composée de plusieurs conditions de sélection logiquement enchaînées et destinées à la spécification de données de sortie, est posée à un système de banque de données. Une pondération d'insuccès est associée à chaque condition de sélection. Si la condition de filtrage n'est pas satisfaite, on détermine la principale condition de sélection non satisfaite par comparaison avec la pondération de l'insuccès.
