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...

Models are a valuable knowledge asset for an enterprise. An enterprise model repository can improve sharing of enterprise knowledge and thus can exploit the use of the knowledge for various applications. In this work we present a framework for the organisation of enterprise models. The framework was derived from enterprise architecture frameworks. It distinguishes three dimensions: aspect, pers...

Lapalme describes enterprise architecture as if it implements one of three completely different viewpoints, however Burk at OMB described enterprise architecture as having three different levels. Related, the PMBOK describes three levels of management. Hite at GAO describes a fourth process of managing enterprise architecture itself. This paper presents a unified view, with five total enterpris...

Existing approaches to architecture description need to be enhanced as they fail to fully capture the unique characteristics of an enterprise system. T he architecture of a system is a specification that captures the structure and functionality of the system in an abstract manner. The specification should help various stakeholders to understand and analyze different functional and quality of se...

ion of services means that “service contracts only contain essential information and information about services is limited to what is published in service contracts”. Therefore, it is always a good practice to design services by hiding as much underlying details as possible. This assures and complements the previous loose coupling SOA principle. Therefore, the avoidance of providing any unneede...

This paper demonstrates a toolset developed by the authors to enable a machine-readable REA ontology specification. Information modelling techniques are used to provide a unified enterprise ontology by capturing the business semantics using Conceptual Graphs (CGs) using Common Logic (CL) and the Conceptual Graph Interchange Format (CGIF) dialect for information exchange and transmission. Formal...
