質問 5：
Jose is designing web services that will return very large record sets (in the 1000's). He is also designing an IBM Web Experience Factory application to consume them and plans to use Web Experience Factory's Paging features to paginate over the large record sets. How should paging be configured for the web services?
A. He should consider using The Chunked Data Retriever builder, which allows you to specify a start index and fetch size before invoking a web service.
B. He should use enable the Web Service Call to return a DataRetriever and then add a Paging Assistant builder and point to the variable created by the results of the web service call.
C. Jose should consider implementing a start index and fetch size parameter in his underlying web services that return large record sets. Then in Web Experience Factory he can implement the DataRetriever interface which enables the Paging Assistant builder to return "chunks" from the underlying service rather that marshalling the entire record set into the application server's memory.
D. He should simply enable paging in the Data Column Modifier builder. Web Experience Factory automatically chunks the data from the backend web service into the app server memory.
