Final answer:
The plural attributes of an entity named Stadium with the primary key SeatNumber will move to a new table called SeatReservations, which handles seat assignment details and maintains data integrity as per the First Normal Form (1NF).
Step-by-step explanation:
During implementation, when modeling a database that includes entities with plural attributes, the best practice is to move these plural attributes into a separate table to maintain the principles of database normalization. The new table created to handle the plural attribute is typically named by combining the name of the original entity and the attribute, suggesting a relational context. In this case, the entity named Stadium contains a primary key SeatNumber and a plural attribute SeatReservation. Therefore, the plural attributes would be moved to a new table named SeatReservations.
This new table SeatReservations would likely have at least two columns: SeatNumber, which would serve as a foreign key linking back to the Stadium table, and another attribute to identify the actual reservation details (e.g., SpectatorID or ReservationID) which uniquely identifies each seat assignment. The association between the Stadium and the SeatReservations table would ensure each seat assignment is unique, much like a ticket specifying a gate number, section number, row, and seat number at a sports event, to avoid any double-bookings for the same seat.
Considering the process of database design, creating a table such as SeatReservations follows the rules of the First Normal Form (1NF) where each column must contain atomic values, and each cell must be unique. Therefore, by moving the plural attribute SeatReservation from the Stadium table to a new table, we maintain data integrity and allow easier and more efficient data management practices.
