Abstract :
A visual query language, designed to be used in a hospital information system is presented. The language exhibits a high degree of adaptation to all kinds of users, as well as a powerful set of tools to formulate queries. It appears to be very simple to learn and it is especially suited to object oriented models. We have also developed a textual language equivalent to the visual one and we have made a comparison with relational algebra.
