Conceptual Modeling and Integration of Static and Dynamic Aspects of Service Architectures

The concept of service is comprehensible in various domains and it can be used for integrated modeling of business process and business data. Service-oriented modeling approach, which is presented in this paper, is based on a single type of diagram. It helps to reason about semantic integrity of different modeling dimensions across organizational and technical system boundaries. A well-known case study is analyzed to demonstrate how service interactions among enterprise organizational components can be represented for detecting the essential similarities and differences of business processes. The ultimate goal of this paper is to overview deficiencies of conventional modeling approaches and to present generic principles for computation neutral modeling of service architectures. Conceptual models of service interactions between organizational and technical components enable separation of crosscutting concerns in enterprise engineering without requirement to specify a complete solution. However, most information system methodologies are projecting the structural, interactive and behavioral aspects into totally different modeling dimensions. If service architectures are represented as loose collection of models, it is difficult to detect integrity problems of various diagrams.
