In Dabo, it's quite a bit simpler. In the UI, you would bind the text
controls to columns in the SalesCustomer table by specifying two
properties: DataSource (the table name) and DataField (the column in
that table).
This would both populate the text boxes from the source as well as
propagate changes in the text boxes back to the source. To create a
new record, you'd call the form's new() method, and then edit the text
boxes normally. To save, call form.save(). Transactions, validation,
etc., is all handled for you.
