Answer:
"this" keyword representing the class object itself.
Explanation:
Object-oriented programming concept emphasizes on using blueprints representing the structure of a data collection type to continuously create an instance of that data structure. The instance of that object is called a class object. It is used in database management systems to populate the database.
Functions defined in the class objects are called methods and are used specifically by the class instance to modify the data content of the class object defined.
When a member of a class is referenced in the class, it can be accessed with the "this" keyword. At an instance of the class object, the variable holding the object should be called to get the class content because of the "this" keyword binding the instance of the object to the method.
Answer:
study-time survey, project schedule, prioritize tasks, reward system.
Explanation:
Time management can be defined as a strategic process which typically involves organizing, planning and controlling the time spent on an activity, so as to effectively and efficiently enhance productivity. Thus, when time is properly managed, it avails us the opportunity to work smartly rather than tediously (hardly) and as such making it possible to achieve quite a lot within a short timeframe. Also, a good time management helps us to deal with work-related pressures and tight schedules through the process of properly allocating the right time to the right activity.
Hence, time-management techniques work most effectively when performed in the following sequential order; study-time survey, project schedule, prioritize tasks, and designing (creating) a reward system.
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.
I have a kindle paper white that I downloaded all of my avalible textbook onto if that helps I find it much better then carrying around a bunch of textbooks
In traditional programming, doubtless the
error-handling outcome that is most often used was to terminate the program<span> in which the
offending statement occurred, or at least to terminate the module (if not the
entire program) in which the offending statement occurred.</span>
