Die Identifizierung von wiederverwendbarem Source-Code für die Implementierung von SOA Services ist noch immer ein ungelöstes Problem. Diese Masterarbeit beschreibt einen Ansatz zur Identifizierung von Legacy-Code, der für eine Service-Implementierung geeignet ist. Der Ansatz basiert auf dynamischer Analyse und dem Einsatz von Data Mining Techniken. Im Rahmen des SOAMIG Projekts wurden durch dynamische Analyse Geschäftsprozesse auf Source- Code abgebildet. Der große Umfang der daraus resultierenden Traces macht eine Nachbearbeitung der Ergebnisse notwendig. In dieser Masterarbeit wurde die Anwendbarkeit von Data Mining Techniken zur Nachbearbeitng der dynamischen Traces untersucht. Zwei Data Mining Verfahren, Cluster-Analyse und Link- Analyse, wurden auf die dynamischen Traces einer Java/Swing Beispielsoftware angewendet. Die Ergebnisse deuten auf eine gute Verwendbarkeit der beiden Data Mining Techniken zur Identifizierung von Legacy-Code für die Service-Implementierung hin.
With the ongoing process of building business networks in today- economy, business to-business integration (B2B Integration) has become a strategic tool for utilizing and optimizing information exchange between business partners. Industry and academia have made remarkable progress in implementing and conceptualizing different kinds of electronic inter-company relationships in the last years. Nevertheless, academic findings generally focus exclusively on certain aspects of the research object, e.g. document standards, process integration or other descriptive criteria. Without arncommon framework these results stay unrelated and their mutual impact on each other remains largely unexplained. In this paper we explore motivational factors of B2B integration in practice. In a research project using a uniform taxonomy (eXperience methodology) we classified real-world B2B integration projects from a pool of over 400 case studies using a pre-developed framework for integration scenarios. The result of our partly exploratory research shows the influence of the role of a company in the supply chain and its motive to invest in a B2B solution.
Expert-driven business process management is an established means for improving efficiency of organizational knowledge work. Implicit procedural knowledge in the organization is made explicit by defining processes. This approach is not applicable to individual knowledge work due to its high complexity and variability. However, without explicitly described processes there is no analysis and efficient communication of best practices of individual knowledge work within the organization. In addition, the activities of the individual knowledge work cannot be synchronized with the activities in the organizational knowledge work.rnrnSolution to this problem is the semantic integration of individual knowledgernwork and organizational knowledge work by means of the patternbased core ontology strukt. The ontology allows for defining and managing the dynamic tasks of individual knowledge work in a formal way and to synchronize them with organizational business processes. Using the strukt ontology, we have implemented a prototype application for knowledge workers and have evaluated it at the use case of an architectural fifirm conducting construction projects.
