While at a lecture, Mr. Selby explained the importance of the three (3) major subsystems of the Transaction Processing System (TPS) that processes a firm's economic activity, he stated that: If you purchase the new iPhone x from amazon.com, you exchange money (in the form of credit/debit card) for the iPhone X. If your credit is good, a series of related operations ensures that you get the phone and the seller gets your money. However, if a single operation in the series fails during the exchange, the entire exchange fails. You do not get the phone and the seller does not get your money. The technology responsible for making the exchange balanced and predictable is called transaction processing: As class captain you are tasked with the following: a.
