A form is not a "control". Forms do not have DataSource or DataField
properties.
In the 3-tier design, the form is the sole interface between the UI
and the bizobj tiers.

In both cases (controls and bizobjs) it refers to the "source" of
its "data". Bizobj get their data from the table, while controls
(typically) get their data from the bizobj. In both cases it means
exactly the same thing; because they are in different tiers, though,
their sources are necessarily different.
