| Abstract: | A method is described for systematically deriving from a static formulation of a simple existence constraint the corresponding dynamic formulation. The latter formulation is embedded, under the form of applicability conditions, in a set of axiomatized update operations. A many-sorted first-order predicate calculus is used as the specification language. Update behaviour issues are identified and discussed. |
