A model is a copy of a query that allows you or other users to produce different reports by specifying different conditions in a copy of the model.
Suppose, for example, that you are the sales manager of Department 38, and you have written a query that lists the name, job, and commission for everyone in your department.
Q.STAFF | NAME | DEPT | JOB | COMM | --------+-----------+--------+-------+------------| | P. AO. | 38 | P. | P. | |
Other sales managers can get a report for their departments by using your model query. They can display, change, and run the query, or change it and run it later.
