Data in Flows

Data is normally passed in both directions along the flow. View matching on the flow specifies that the data needed by the receiving procedure be passed between a client and a server procedure. A well-designed client/server application should minimize network traffic. When you match views on a flow, move only essential information between the two procedures.

The data to be passed along a flow is defined using view matching. By introducing a work attribute view in the server procedure and a corresponding view in the client procedure, you can return the server procedure execution status to the client procedure for interpretation. The interpretation is performed by a CASE OF statement in the client procedure.
