If you don't want to use it, don't include it ;) If this is running as web app, you can use header [1] and pass the criteria for next phase of the operation as URL parameters. But doing this is going to kill the server side with too many unnecessary round trips. Which clearly demonstrates point 2 and 3. You should look into Interfaces, and Abstract under OOP [2].
