“…Because of the huge amount of data a standardized archive and catalogue of all existing certificates of explosion proof equipment is planned which will be integrated in a software package called CATC (Computer Aided Testing and Certifying). Since 1994, the design and modelling of CATC is the long-term aim of the cooperation between the PTB and the database group of the Technical University of Braunschweig [25,24,19,33]. As now, we have not applied any tool support to the modelling process of our system.…”

In this paper, we present a set of software tools for developing and validating object oriented conceptual models specified in TROLL. TROLL is a formal object-oriented language for modelling information systems on a high level of abstraction. The tools include editors, syntax and consistency checkers as well as an animator which generates executable prototypes from the models on the same level of abstraction. In this way, the model behaviour can be observed and checked against the informal user requirements. After a short introduction in some validation techniques and research questions, we describe briefly the TROLL language as well as its graphical version OMTROLL. We then explain the system architecture and show its functionalities by a simplified example of an industrial application which is called CATC (Computer Aided Testing and Certifying).

Abstract. Observers are objects inside or outside a concurrent object system carrying checking conditions about objects in the system (possibly including itself). In a companion paper [EP00], we show how to split and localise checking conditions over the objects involved so that the local conditions can be checked separately, for instance using model checking. As a byproduct of this translation, the necessary communication requirements are generated, taking the form of RPC-like action calls (like in a CORBA environment) among newly introduced communication symbols. In this paper, we give an algorithmic method that matches these communication requirements with the communication pattern created during system specification and development. As a result, correctness of the latter can be proved. In case of failure, the algorithm gives warnings helping to correct the communication specification.
