Do queries store data?
No. Only your tables store data. Queries, Forms, Reports and Pages can just do things like display the data and manipulate it but, the data is always stored in the tables. When you run a query, open a report or a form, the data you see is ultimately coming from underlying tables. You can do queries on queries, or reports on queries or forms on queries but the original data always comes from the tables.
