Fundamental Patterns for Enterprise Integration Services

Abstract

Enterprise integration projects link or merge artifacts across many functions, processes and management levels in a company or government agency. In the absence of methods generic enough to cover the diverse range of enterprise integration projects and adaptable enough to support specific projects effectively, integration services promise to constitute a suitable “middle layer”. Since patterns and reference models could serve as such a middle layer, existing work in the fields of patterns in computer science and reference modeling in information systems engineering is analyzed. In a bottom-up manner, alignment, derivation, binding and merge are proposed as fundamental patterns for enterprise integration. Integration services are identified as integration tasks associated with these base patterns. Such integration services are clustered into enterprise integration patterns that serve as fragments for composing a context and project type specific enterprise integration project. Two case studies illustrate the concept and gain initial validation insights.
