for Enterprise Application Integration Today’s enterprise applications must be highly scalable and equipped for growth — adaptable and extensible enough to manage both current and future business systems and processes. With service-oriented architecture, IT organizations have a variety of options for integrating their infrastructure — from point-to-point and hub and spoke approaches, to an ente...

Enterprise systems are being transferred into a service-oriented architecture. In this article we present a procedure for the integration of enterprise systems. The procedure model starts with decomposition into Web services. This is followed by mapping redundant functions and assigning of the original source code to the Web services, which are orchestrated in the final step. Finally an example...

Enterprise architecting is a complex process that includes incorporating knowledge, processes, systems, technologies, and people. In order to ensure the appropriate value integration in this complex process, key fundamentals for value integration need to be explored and studied in this context. Previous research has shown that architecture management and business strategy are still largely disi...

The integration of enterprise information systems has unique requirements and frequently poses problems to business partners. We discuss specific integration issues for micro-sized enterprises on the special case of independent sales agencies and their suppliers. We argue that the enterprise information systems of those independent enterprises are technically best represented by equal peers. Th...

To serve its purpose as a backbone for business integration, Enterprise Resource Planning (ERP) systems need to be integrated with other information systems inside and outside the boundaries of an enterprise. An inductive case study was made to examine a long-term ERP system of a large manufacturing enterprise to better understand the nature and importance of ERP system integration. Our results...

The discipline of enterprise application integration (EAI) enables the decoupled communication between (business) applications, and thus became a cornerstone of today’s IT architectures. In 2004, the book by Hohpe and Woolf on Enterprise Integration Patterns (EIP) provided a fundamental collection of messaging patterns, denoting the building blocks of many EAI system implementations. Since then...
