Different views of the same fields

For one the same object there may be several views: for example, in a
"database" view empty fields may be signified by `undef` (to denote
NULL in an SQL database) and in "UI" view they may be denoted as empty
strings.

Is my idea: new, is it viable? Is it (or will it be?) implemented?

Tell anything you think about this idea.
