No, you don't. A view is another way of looking at the data. In SQL, the
index may be built for the query or you may just want arrival sequence of
the file. The purpose of the view (keyed or not) is to provide either a
different order of fields, a different mapping of fields, changing
attributes of a field or subsetting the list of fields that are "viewed"
through the file.
