You are working on a new product that will provide an online pizza ordering service. Not everyone wants to create a frequent-eater pizza account, so the user can either log in to their existing account, create an account or proceed as a ''guest' user. People with existing accounts have the option to update their accounts including changing address, changing credit card information and changing phone number. New account creation requires the user to enter their address, credit card information and phone number. This information Is validated to be sure the address matches the credit card information.

Once the user logs in, they are able to order their pizza. They can request up to five different pizzas and can select different ingredients on each. A user is allowed to pick up to 10 different ingredients per pizza. They can also select from a pre-defined set of ingredients as follows: ''meat lovers', ''all veggie', ''cheese please', and ''throw it all on'.

The busiest day of the year for this product will be the day of the final football game of the professional season. In addition to the normal high load, the company will also be running a special on the ''cheese please' pizza (buy 3 get 2 more free). The new product will need to handle a load that Is expected to be twice as high as the load on the old product last year.

Explanation:

Considering the high load expected on the busiest day, particularly with a promotional offer like ''buy 3 get 2 more free'' on a pizza, addressing transaction concurrency in the architectural specifications is crucial. This ensures the system can handle multiple and simultaneous user transactions efficiently without data loss or service degradation. Proper handling of transaction concurrency is essential to maintain system integrity and responsiveness during peak times, which is a critical requirement for the online pizza ordering system on such a high-traffic day.
