This process consists of the actual business operations performed
on a customer account. The bank teller can use the teller
application to identify the customer and get information about the customer's accounts, and allow the customer to make a deposit or a withdrawal on a personal
account and to ask for an account statement.
Each of these operations has part of its execution on the client
side and part on the server side. The following is the process flow:
- The client side builds a request that arrives at the server and
starts its execution.
- The server inserts a record into the Electronic Journal and sends
a formatted buffer to the host.
- When the host transaction is completed, the server unformat the returned data from the host and updates the Electronic
Journal with the transaction result.
- The server returns the reply to the client.
- The client displays the appropriate information or confirmation.
