You can even do it without using 2 separate tables or using nested
tables. It can be done in one single table (if you don't mind that this
table isn't bound to specific Dataset) and 2 DataElement's, each bound
to its appropriate DataSet. This approach is useful if you have a lot of
data from a lot of datasets that you want to join in just one
table(without nesting, joined datasets, etc.) Here's an example:
