Towards the integration of ExSpect and S-Cort: a case study

PROOFS project aims to develop a method for heterogeneous distributed applications (HDA) design, including formal techniques of specification. The skeleton of the PROOFS method is based on the use of the S-Cort method developed by SLIGOS. Nevertheless some additional developments of this method are required in order to satisfy the initial objectives of PROOFS project. This article deals with the insertion of a functional architecture specification in the current HDA design process described by S-Cort. To introduce such an architecture, the authors propose the use of ExSpect formalism and tool. This solution is presented through a case study (a teleshopping application) and as a result of this experimentation, some ExSpect formalism improvements are proposed in order to increase the suitability of this solution
