FLOWS are about PROCESSING! Two Aspects of Data Exchange:FormatData Container XML Schema ProcessRules surrounding the flow of data More complex than creating a format Can we have XML-based processinginstructions?
The “Ideal” Data Flow ScenarioOne Owner/Authority for a givendataset Each owner publishes to their node Nodes each provide a commoninterface for given data flow
The “Ideal” Data Flow Scenario Data Consumer should initiateRequests from the Data Provider“Come and get it” approachOnly the consumer knows what itneeds and when it needs itDataConsumerNodeWant MyData?No No No DataProviderNode
The “Ideal” Data Flow Scenario Data Provider should need NOknowledge of Data Requestor’sstate Complexity of storing data consumer’sstate on the provider sideNot as scalableDataConsumerNodeGimme the DataI Don’t HaveNope. Tell mewhat you want!!!DataProviderNode
The “Synchronization” Data Flow Scenario Push or Pull will workShould all happen in the backgroundOnly require user intervention when andexception occursDifficult to achieve when synchronizingheterogeneous systemsCrosswalking data what a mess!
