Software application program, software architecture and method especially for producing software application program for MES system

Objects (with data, attributes, behavior, functions) for software applications, especially MES-applications, are linked to meta information and structured as hierarchical trees (whereby different forms of representation can be selected) and are branched or cross-linked together (laterally and/or horizontally). During the running time, the objects are added to form software applications whereby the common functions of the software applications are derived from the structure of the hierarchical trees. Software applications for MES-systems are constructed for automation systems, for industrial controls (also movement controls) and for office applications (office area).
