Similarly, there are alternative approaches to selection of data items
As the number of hosted data sets grows, so does the confusion over ‘which items are in which data sets’.
This example shows selection of pre-aggregated totals. Note that some of the options are ‘greyed out’ - this reflects the choice of the USA in the previous screenshot: data sets which do not include a USA origin are removed from the set of choices.
Other data selection methods:
List of data sets and included cross-tabulations
List of variables: e.g. select ‘age’ and the user is shown a list of all table in all data sets in which age is used. The display also shows other variables that are cross-tabbed against age. The user can (recursively) select one of these in order to narrow down selection of an appropriate table.
