Displaying data from multiple datasets in the same table

I have two datasets, the first one attached to a table, and I would like
to display a field from the second dataset based on a criteria. Think as an
analogy to joins, but for various reasons I cannot merge the queries to get
a single dataset (data is coming from different databases). So, I have a
common key and I want to lookup into the second dataset? How can I achieve
that?
Practical example: first dataset retrieves a list of people, with their
address and a column the contains the country code. In a different DB I have
a table that has associations for a country code a country name. How can I
display a list of people and the country name? No join at query level is
acceptable.
Regards,
MariusA data region can only be bound to one dataset. Why is a join in a query
unacceptable? Can you create a view in your database with a join in it and
create a dataset off of that view? Would that be an acceptable alternative?

custom data extensions that gets data from our business layer objects. In
business layer we do complex calculations, so writing the reporting as pure
SQL queries wouldn't be feasible. So we have business layer object that
retrieves a list of persons, and a business layer that retrieves a table
with mapping from country codes to names. We would prefer not to implement
joins in our custom data extensions if it would be possible. Also, I guess
that subreports would do it, but is seems to be that it would be an
overkill, and would raise problems when going to numeric (orders with items,
and items with prices in a different dataset), because for example we could
have two different tables, and show the difference between two prices.
