For the Cash Register system that was extensively discussed in class $($if you forgot the requirements of this

system they are posted in Canvas.$)$ the shop owner now wants to make some changes to the existing

system.

Perform steps $4$ to $6$ in the ADD process to create a revised architecture. I expect to see a revised

architecture diagram, a description of any new elements and their responsibility, a sequence diagram

depicting UC$-1$ and a description of the "new" methods.

Description

The existing cash register system is a local standalone application system designed to manage purchases of

items at a store.
