5. Goals in healthcare business
   Intelligence via information sharing
   Decrease latencies in connected services
   Providing the best possible service through accurate and timely
   information sources
   Reduce manual executions to reduce human errors (i.e data
   entry etc.)
   High availability of medical information
   Big data analytics for healthcare research

7. Technology landscape in healthcare
   Heterogeneous devices / applications / data formats
   / protocols (i.e hospital information system)
   heterogenous integrations in a hospital

8. Devices & Services
   Classic use-case where devices and services
   connects to a private cloud

9. Protocols & Data formats
   HL7 (v2 / v3 / FHIR) over HTTP
   SOAP / XML over HTTP
   REST / JSON over HTTP
   Messaging over JMS
   XML, CSV over FTP
   Custom binary protocols (certain HC devices)
   Legacy CORBA based systems

10. Interoperability
    Interoperability issues are solved via a bus architecture
    in Health Care Information System (HCIS)
    interoperability with healthcare bus architecture

11. Data federation & mediation
    In a distributed HCIS data can reside in multiple
    different locations
    Some data needs to be consolidated before
    consumption
    Aggregation of data can be a function of data
    federation and service mediation

13. Data governance & entitlement
    Distributed transactions (maintaining the
    ACID properties in health data)
    Who can access the data
    From where the data is accessed
    Entitlement policies
