Architecture of Interoperable Information Systems
An Architecture of interoperable information systems describes how interoperating information systems can be efficiently designed and implemented. The problem of interoperating information systems is tackled since the invention of information system, and many concepts were created to foster interoperability betweent different kind of information systems. In 2010, under the name "Architecture of Interoperable Information Systems" (AIOS) a reference architecture for interconnecting enterprise information system was published. It can be seen as complementary to the "Architecture of Integrated Information Systems", which is a wide-spread architectur for describing information systems and business processes inside one organization.
Definition
The automation of cross-organizational business processes is one of the most important trends of the information age. lnstead of a tight integration however, collaborating organizations rather strive for a loose coupling of their information systems. The information systems should be able to work together but retain as much independency as possible. This characteristic is also called interoperability. In the context of collaborating organizational systems which work together, the term Business Interoperability was proposed. In comparison to interoperability notions that focus on technical systems, this term refers to the capability of autonomous organizations to execute a collaborative business process among them.
Information systems are systems that process information, i.e. they capture, transport, transform, store and offer information. Following the conception prevailing in information systems research, an information system comprises not only the hardware and software of an enterprise, but also the related human actors, business functions and processes as well as organization structures.[1] Architecture is defined as the “fundamental organization of a system, embodied in its components, their relationships to each other and the environment, and the principles governing its design and evolution”[2]
