Even though the arrangement of the fields come from different tables, if your relationships are set up correctly, any data entered will be properly placed in the correct table. Forms will also allow you to ‘restrict’ what users enter though a variety of elements. Input screens, validation rules, list boxes, toggle buttons, etc. limit what the user can enter into your database. This offers a level of security that access to tables and datasheets can’t. Other advantages of forms, as opposed to datasheets and tables, are forms can use multiple tables, and graphics can be displayed.
