S7 Federator
An increasing number of MultiValued applications involve integrating data from multiple data sources and point-to-point domains and devices. In such an environment, these data sources can be fairly dynamic due to Source Failure.
S7 Wrapper works to mask applications performance from this challenge which includes communication with a variety of unusual data sources within our client topology. These custom routines, including the interaction with EDI transmissions, can be integrated with DataStage jobs for the production environment.

Strategy 7 Federator also includes communication routines for hand held barcode and RF devices. This means that the queries may not specify data sources directly, but instead be dynamically bound against the right set of data sources and replicas at run time. The data sources are chosen based on the query predicates, and the replicas are chosen based on the application's staleness tolerance (specified as part of its QOS requirement). Depending on the application's QOS needs, the DBMS should also mask data source failures during query execution, by gracefully degrading the query results into partial query results.
