Abstract: An apparatus for communicating with a plurality of remote machines, of a plurality of machine types includes a computer system including a processor and memory a data communication means, coupled to the computer system and to the plurality of remote machines, for communicating with each of the plurality of remote machines, a first plurality of software objects within the memory for describing services for the plurality of remote machines, and a plurality of operations within the memory associated with the first plurality of software objects, the plurality of operations for satisfying requests described by the services of the first plurality of software objects.

Abstract: A system enabling an application programmer to construct a plurality of application programs for communicating with a plurality of remote machines of a plurality of machine types, each of the plurality of remote machines having remotely accessible data and remotely performable operations includes a computer system with a memory, a processor, and a mass storage device, the computer system for storing programs, class declarations, and class libraries in an object-oriented programming language, means for compiling files containing source-code representations of application programs in the object-oriented programming language, implementations of a hierarchy of data description classes, each implementation for describing a set of data and for describing methods for manipulating the set of data, implementations of a hierarchy of remote data description classes, each implementation for describing data items contained in one of the plurality of remote machines and for describing methods for accessing the data items,

Abstract: A method for communicating with a plurality of remote machines, of a plurality of machine types, using a computer system having a memory, includes the steps of constructing within the memory a first plurality of software objects, the first plurality of software objects describing services for one of the plurality of remote machines, establishing communications with the one remote machine, and invoking operations on the one remote machine in response to requests described by services of the first plurality of software objects.
