Explain the advantage of creating a form with a subform.
What will be an ideal response?
When you use the Form tool to create a form, Access analyzes the table relationships in the database. If the table that the form is based upon is related to another table, Access automatically adds a subform to the main form. The subform displays records in the related table, generally organized in a datasheet format. For example, assume you have sales representatives stored in a Sales Reps table and related customer information stored in a Customers table. In this case, if you create a new form based on the Sales Reps table using the Form tool, Access will add a Customers subform to the bottom of the main form, displaying all customers assigned to each sales representative. You can modify records in both the main form and the subform.
