Access as a Prototyping Tool
• Since it is relatively easy to create mockups of forms and reports using Microsoft
Access wizards, such mock-ups are often
developed even in situations where
Access is not going to be used as the
operational DBMS
• The mock-ups are used as a prototyping
tool to demonstrate the consequences of
data modeling decisions

The Access Banded Form and Report Editors
• Access uses banded form and report editors
– Each element of the form or report is displayed in its
own band such as Header, Detail, or Footer, which
makes such rearranging very easy to do.
– These can be resized as necessary, as can the size of
the entire form or report itself
– The size and position of any subform area within the
report can also be resized
– The labels and text boxes that display the data can be
moved or resized using standard windows drag-anddrop actions
– Label text can be edited, and additional labels or other
text added
