Figure 1.

The basic form interface generated for ACT/DB. There are three frames in a “frame set.” The top “leader” frame displays demographics data with, optionally, a set of buttons to enable navigation within the second form. The middle “detail” frame is where data browsing and editing are actually done. The bottom “toolbar” frame is shared across all data entry forms: the forms generator generates only the header and detail frames. In the figure, the user has clicked on the “Prior Chemotherapy” button in the header frame, causing the detail frame to scroll to the subform for Prior Chemotherapy.
