The 4gl languages that enable non-programmers to use certain easily understood commands to search and generate reports from a database are called <u>query</u>.
<h3>What is 4gl?</h3>
A computer programming language that is part of a class that is intended to improve upon third-generation programming languages (3GL) is known as a fourth-generation programming language (or 4GL).
Every generation of programming language strives to provide a greater level of abstraction of the internal workings of the computer hardware, making the language more user-friendly, potent, and adaptable.
Despite the fact that the definition of 4GL has evolved over time, it can still be characterized by the fact that it works more with large groups of data at once rather than concentrating on just bits and bytes.
The support for report generation, database management, mathematical optimization, GUI development, and web development may be found in languages that advertise themselves as 4GL. According to some academics, domain-specific languages include 4GLs as a subset.

Answer:
import
Explanation:
the <em>import </em>keyword is used to import external modules into a python script.
In this exercise we have to use the knowledge in computational language in python to write a code with circles and squares.

Answer:
=(A4+B4+C4+D4+E4)/5
Explanation:
If we want to have the average of the passengers, first we must sum all the revenue and then divide it with passenger quantity.
In this particular example, I made the formula with 5 passengers, I sum the 5 revenues and then I divide with 5 passengers if there are more passengers we must sum all of them, and divided all of them, for example:
=(A4+B4+C4+D4+E4+F4)/6
It really depends on your type of data, if it's sensitive data or not. And it also depends on what type of backup (Incremental, Decremental, etc.). But you should aim to backup at least once a week, and also do a backup of your original backup.
