Control and coordination of heterogeneous transaction processing systems

Transaction processing systems (TPS) applications are a large component of most business organizations' investment in computer technology. Heterogeneous and distributed computing environments have become essential and beneficial to most corporations. Thus, there is a need for tools to support the development of new distributed TPSs and the migration of existing TPSs to distributed environments. This paper presents the design and construction of a software tool that provides the functionalities necessary for the construction, operation and management of heterogenous distributed TPS applications. The tool design is based on object-orientation and real-time control and is implemented using Prolog and C. We anticipate that the tool will provide practical and significant benefits to the operators and maintainers of large-scale TPSs.
