Kopplungsarchitekturen zur überbetrieblichen Integration von Anwendungssystemen und ihre Realisierung mit SAP R/3

Business-to-business processes require an inter-company integration of the application systems supporting these business processes. Integration is based on inter-company couplings of application systems, which are specified in coupling architectures. The necessity of coupling of application systems arises from relationships between business tasks which are to be supported by these application systems. Starting with relevant relationships between business tasks, three classes of coupling architectures are identified and illustrated by concrete instances. It is investigated to which extent coupling mechanisms as provided by SAP R/3 are suitable for an implementation of these coupling architectures.
