Data Refinement and Simulationsesence of inputs and outputs. Furthermore, other “simple refinement” rules were given whose justification was postponed to the general data refinement theorem, to be presented in this chapter and formulated in Z in the next. Apart from that, the following issues were not fully exposed:

Refinement in Znd downward simulations and, finally, how simulation rules for partial operations are derived from these. All of the questions listed at the beginning of Chapter 3 have now been answered, with the exception of the one concerning input and output.

Calculating RefinementsIn the examples we have looked at so far we have used simulations to verify refinements. This has involved writing down the concrete specification, postulating a retrieve relation, and then verifying the conditions necessary for a refinement to hold.

An Introduction to Object-ZObject-Z is an object-oriented extension of the specification language Z, which has been developed over a number of years and is one of the most mature of all the proposals to extend Z in an object-oriented fashion.
