A visual query language, designed to be used in a Hospital Information System is here presented. The language exhibits an high degree of adaptation to all kinds of users, as well as a powerful set of tools to formulate queries. It appears very simple to learn and it is especially suited for Object Oriented models. We have also developed a textual language equivalent to the graphical one and we have made a comparison with relational algebra.

Abstract
A visual query language, designed to be used in a Hospital Information System is here presented. The language exhibits an high degree of adaptation to all kinds of users, as well as a powerful set of tools to formulate queries. It appears very simple to learn and it is especially suited for Object Oriented models. We have also developed a textual language equivalent to the graphical one and we have made a comparison with relational algebra.File in questo prodotto:
