Starting from a graphical data model (a subset of the OMT object model), a skeleton of formal specification can be generated and completed to express several constraints and provide a precise formal data description. Then standard operations to modify instances of this data model can be systematically specified. Since these operations may invalidate the constraints, it is interesting to identify their preconditions. In this paper, the ZEVES theorem prover is used to calculate and try to simplify the preconditions of these operations. Then, the developer may identify a set of conditions and use the prover to verify that they logically imply the precondition. Y. Ledru. Identifying preconditions with the Z/EVES theorem prover.
