Unisys Corp has decided to forego the benefits of confining its Mapper applications generator and Ally language and tools to its own hardware, and is to offer them to users of Sun Microsystems Inc’s Sparc-based workstations and servers from September. It will market them to Sun users via Foundation Computer Systems Inc, a wholly-owned Unisys subsidiary. Unisys claims that Mapper is up on over 5,000 of its mainframes and Unix systems. Ally is a database-independent language and set of tools which can access Oracle, Informix, C-ISAM, Sun’s NetIsam and Mapper within the same application, and provides windowing capabilities on asynchronous terminals. Unisys is planning a Unix-based open software architecture for all its products.
