Service Oriented Architecture Service providers registersh services to a service broker. Service users find the needed service and get access key from a service broker With the access key, users bind to the service provider The result is a dynamic binding mechanism between the service users and providers Service Broker Service Provider Register by ISO “Harvests by CSW” CSW Access Service User Components:Provider – User – Broker Actions: Publish – Find - Bind ISO

The data life cycle consists of the acquisition and the usage parts Usage ActivitiesData Acquisition Data Acquisition and Usage Activities (Select View Show, click to step through PPT) The acquisition part processes the sensory data by firmly linked procedures The focus is on data usage activities The usage activities are more iterative, dynamic procedures The collected and cleaned data are stored in the repository Data Repository The usage cycle transform data into knowledge for decision making Decisions
