When you add, change, or delete a record in a form, how does it affect the underlyingtable? Why?

What will be an ideal response?

When you add a record to a form, you are actually adding the record to the underlying table. Similarly, when you change or delete a record in a form, you are changing or deleting the record in the underlying table. This is because data is not actually stored in the form. The form simply gives you another view of the data in the table.
