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: I believe the correct order is:
Create a box and title it as the “Home Page” → Branch out pages and specify navigation flow → Gather information such as text and images → Determine the title, heading, and content for each page → Draw a layout of each web page with its elements.
Explanation: It makes sense, you start with your "Home Page", then you follow the steps of planning to map out your site's navigation. You have to gather information about it before you have enough knowledge about it to determine the title, heading, and content. You also need to know the content to create a clean and workable layout for the page.

Answer:
variable when the component is mounted. This triggers the watchers which then triggers an emit i have in the watcher. I do not want the emit to happen when the variable is only being initialized. The variable is from the data section of the vue component.
