I added those value objects to show how you would send data to the
server and receive data back in the form of objects.
At some stage in the future you will find that you need to send
multiple parameters to the server and this shows how you would do
that. If you only need to send one parameter, a string would suffice
and you don't need value objects. The same thing can be said if you
are only receiving a string back.
Generally, I receive an array of objects back (say from a MySQL query)
that I will then bind to a datagrid. It is a lot easier to understand
the code if the objects have a specific name and structure. It also
makes it a lot easier to update the code if you have to add another
parameter in your object.
