Zusammenfassung der Kapitel (Chapter Summaries)

• Introduction: This chapter introduces the thesis, outlining the motivation, objectives, structure, general conventions, and cooperative aspects of the research.
• Basic Principles: This chapter explores foundational concepts related to information and application systems, including their architecture and principles. It delves into the concepts of information systems, the levels of tasks and task bearers, business tasks, application systems, and distributed systems.
• Service-Oriented Architecture: This chapter introduces the concept of service-oriented architecture (SOA), its principles, and its implementation. It examines the meta-model, reference model, and definition of SOA, while also discussing the implementation aspects of SOA.
• SAP's Enterprise Service-Oriented Architecture: This chapter focuses on SAP's approach to enterprise SOA. It explores the basic concepts, definition, and technology environment of enterprise SOA, including the NetWeaver overview, Composite Application Framework, and Visual Composer.
• Approach to Design and Implementation of an SOA: This chapter outlines the methodology for designing and implementing an SOA, including the Semantic Object Model (SOM) and its application in specifying business systems and business application systems. The chapter further delves into the technical design for implementation with SAP NetWeaver, including the creation of processes, implementation of back-end web services, and implementation of composite services and user interfaces.
• Design and Implementation of the Case Study Architecture: This chapter presents the design and implementation of a specific case study architecture, outlining the technical environment, scenario, and design specifications. It provides a detailed explanation of the implementation process, including the use of CAF Guided Procedures, back-end web services, composite services, and Visual Composer. The chapter also discusses the evaluation of both the design and implementation phases.
