Answer:
Hi Riahroo! This is a good question on the concept of relational databases.
We can normalize the relations as follows:
Flight
(flightnumber (unique), flighttime, airline_id, departure_city, arrival_city, passenger_id, pilot_id, airplane_id)
has_one_and_belongs_to :airline
has_many :passengers
has_one :pilot
Itinerary(passenger_id, flight_id)
Belongs_to
Passenger_details
(passengername (unique), gender, date_of_birth)
has_many :flights
Pilot
(pilotname (unique), gender, date_of_birth)
has_many :flights
airline(airlinename)
airplane(planeID, type, seats))
Explanation:
To normalize a relation, we have to remove any redundancies from the relationships between database objects/tables and simplify the structure. This also means simplifying many-to-many relationships. In this question, we see there is a many-to-many relationship between flights and passengers. To resolve this we can introduce a join table which simplifies this relationship to a one-to-many between the objects.
Answer:
Long-term memory
Explanation:
There are two common types of memory - Long-term and short-term.
In short-term memory, information are stored just for a very short time before they are eventually discarded or transferred to the long-term memory. It is sometimes called working memory. For example, short-time memory can be used to remember that a particular event is going to be by 12pm today. After the event, the information might either be discarded or pushed to the long-term memory.
In long-term memory, information are stored for a very long term, almost permanently. For example, long-term memory enables you to remember an event that has taken place in the past. In the case of Rasheed, he has so much learned the multiplication tables in such a way that information on the tables have been stored indefinitely in a part of his brain called hippocampus. Every time he needs the multiplication tables, they are always available. So he is already taking advantage of the long-term memory.
