Excel as a Development Environment

So when I press the submit button ....

It posts the form to my controller servlet.
which looks for the correct command object to handle the request.
the command object creates a formObject which validates the form and
returns a valueObject by calling billions of setters on the billions of member variables.
the busines facade object grabs the corect Data Access object and passes the value object thru.
the Data access Object fills a preparedStatement by calling billions of getters on the value object and saves the record in the datbase.

sheesh.

So how do you manage all the variables, settters and getters no to mention the create table scripts? Good old fashioned excel of course. Who needs expensive tools or XLST?
