I need a response in your opinion, from this answer Q1. Any user accessing the database is more interested in quick and correct result than how a database is designed. Hence if we introduce redundancy in the table and if the performance of the query increases, then we can ignore 3NF. This is known as denormalization. In this process, a normalized table will be rejoined to have the redundancy in the table to increase the performance of the query. Denormalization...

When people want to be seated in the restaurant, they give their name and group size to the host/hostess and then wait until those in front of them have been seated. The program must use a linked list to implement the queue-like data structure....
