3 Service Oriented Device Architecture (SODA) 3 11/13/07

4 Building the pipeline of real world* data SODA shifts the programming model for an emerging class of enterprise solutions toward SOA and event driven architecture. data driven (healthcare, retail), event driven (asset monitoring) location based (asset tracking, fleet) hybrid and cross industry (supply chain/rfid, DoD, emergency response, bio surveillance) * Common characteristic of these solutions and applications are that they depend upon timely data feeds to and from devices which map phenomena directly from the physical world into digital representations. 4 11/13/07

5 At the simplest level, SODA lets programmers deal with devices such as sensors and actuators just as business services are used in today s enterprise SOAs. SODA converts hardware devices to software services with well-defined interfaces, independent of the programming language and the computing platforms to which they are connected.

20 Stepstone Clinical Drug Trial Scenario Charley volunteers for a trial study of a new drug. Drug manufacturer interested to research weight change from taking the drug. He is given (loaned) a weight scale device. He agrees to weigh himself once a day /13/07

21 Stepstone Clinical Drug Trial Business Measures Patient info: Name, date of birth, sex, race, address Observation result: type (device weight, device activity count, etc.), measurement Number of measurements to date % weight change based on initial weight Alerts % weight lost > 5% % weight gained > 10% 21 11/13/07

24 WBM Features Improve drilling up and down function for further data and trends analysis Take actions for detected alerts Alerts view to show all alerts that required attention or manual action. Admin may /call nurse/doctor or patient to inform them about the alert situation. WBM sends outbound message to cause automated actions, including send an , forward a HL7 message to other healthcare systems for further processing, etc. Create role-base dashboards 24 11/13/07
