Thumbnails which will limit the data extracted from the data
source.
Thumbnails are used to test the data retreval for the
report. Insted of reading entire data base we use Thumbnails
to limit the data
Mostly Thumbnails are used for testing the report.

When you use thumbnails, Impromptu retrieves only the
number of rows you specify and then saves them temporarily
on your computer.
Impromptu attempts to use only the data in the thumbnail
when you run a query. If your query requires information
that is not in the thumbnail, Impromptu accesses the
database and retrieves the information required. When you
close the current report, the thumbnail is discarded.
For example, if you work with a thumbnail of 30 rows,
Impromptu retrieves the first 30 rows from the database and
then uses the 30 rows as the data source for your queries.
If you add a column to the query, Impromptu must retrieve
the new data from the database.
A thumbnail is an efficient way to test your report before
running the query against a large database.
