Abstract

In this paper we present various notions of the combined refinement for data and processes within the specification language Csp-Casl. We develop proof support for our refinement notions and demonstrate how to employ them for system development and for system analysis. Finally, we apply our technique to an industrial standard for an electronic payment system.
