I don't know why you react so emotional.
In any case, such statements as the one above shed some light on you... I hope you feel better after your comment above ;-)

Solution 1

See http://en.wikipedia.org/wiki/Multitier_architecture[^].

As a starting point:
1. Identify what your layers are in your code.
2. Re-arrange such that one layer depends on the next layer only.
