1. The user selects a node.2. If the node is

Problem Statement
Build a specification-level design of the
software to support a computerized banking
network including both human cashiers and ATMs
to be shared by a consortium of banks. Each bank
provides its own computer to maintain its own
accounts and process transactions against them.
Cashier stations are owned by the bank and
communicate directly with the banks computers.
Human cashiers enter account data and transaction
data. ATMs communicate with a central computer
which clears transactions with the appropriate
bank. An ATM accepts a cash card, interacts with
the user, communicates with the central system to
carry out the transaction, dispenses cash, and
prints receipts. The system requires the
appropriate recordkeeping and security features.
The system must handle concurrent access to the
same account correctly. The banks provide their
own software for their individual computers, you
must design the network and ATM software. The
cost of the shared system will be apportioned to
the banks according to the number of customer
transactions per month.
