| Summary: | Extensive efforts are being conducted in the area of integrating and merging together applications and systems in public administration, including healthcare. One approach against integrating applications is to introduce a Service Oriented Architecture (SOA). This could be conducted by modifying the previously stand-alone systems and make them act as services or components, communicating through some sort of common services or directly interoperate. This thesis describes several standards and best practices addressing integration currently present in healthcare. Additionally, a number of business key aspects connected to Service Oriented Architectures are described and also how customers and contractors could benefit from these. By conducting an industrial case study of an integration project, standards and business aspects could be applied and used to analyze the project. Both software engineering issues and business aspects are identified, important to the study.
