Automated Reasoning Tool progenitor Inference Corp, El Segundo, California is developing what it calls an integrated multi-system tool for building enterprise-wide applications. Art*Enterprise, currently in beta test for Windows, will eventually support more than 10 major operating environments including NT, Macintosh, OS/2, MVS and Unix from Sun Microsystems Inc, Hewlett-Packard Co, IBM Corp, Digital Equipment Corp and NCR Corp. The object-oriented software is targeted at companies that are downsizing into client-server and distributed computing environments and re-engineering their processes. Described as an upwards-compatible extension of the Automated Reasoning Tool for Information Management, ART-IM, it offers access to reusable graphical user interface class libraries, data modelling capabilities, intelligent processing technologies and automated integration with legacy systems and data. Prices go from $7,000 according to system.
