Answer:
Dynamo, Bigtable, and Cassandra are NoSQL data stores being used by some of the worlds biggest IT businesses such as Amazon.
These programs were developed to solve a specific or unique business problem. The initial plan was not to commercialize them.

Answer:
The Solution Code is written in Java.
- public class Main {
- public static void main(String[] args) {
- System.out.print("Please enter an integer: ");
- Scanner input = new Scanner(System.in);
- int number = input.nextInt();
- System.out.print("Prime numbers less than or equal to " + number + " : ");
- for(int i=2; i <= number; i++){
- if(checkPrime(i)){
- System.out.print(i + " ");
- }
- }
- }
- public static Boolean checkPrime(int num){
- for(int i=2; i < num; i++)
- {
- if(num % i == 0){
- return false;
- }
- }
- return true;
- }
- }
Explanation:
Firstly, we create a function to check if a number is prime (Line 18 - 27).
- This function will take one input value which is an integer, num.
- To check if the input num is a prime, we can use modulus operator, %, to confirm if the num is divisible by any number starting from 2 to num - 1 (Line 19 - 24).
- If the num is divisible by any number expect 1 and itself, it should equal to zero and return false to indicate it is not a prime number.
- If all the num (except 1 and itself) is not divisible, the function will return true (Line 25).
Next, in our main program part (Line 3 - 16)
- Prompt the user to input a number (Line 5 - 7)
- Using a for-loop, we can keep calling the checkPrime() function by passing a current number (starting from 2 to input number) as argument (Line 12). The checkPrime() function will run and return true it the current number is prime, return false if it is not prime.
- If the checkPrime() function return true, it will print the current number before proceed to the iteration of the for-loop to repeat the same check prime procedure (Line 13)
- At the end all the prime numbers less than or equal to the input number will be printed out in the terminal

A health service, a sales service, a social network, all because they require you to make a request to return a result
Answer:
Here is my answer in Javascript
num = 0; // Use to calcate the even numbers
loop = 10; // Use for the highest even number that will be calcated for
index = loop/2; // Calcate the size of the array based upon how many loops their
let arr = [index]; //Create array to store the even numbers
let i = 0; // Use to keep track of which on what number in the while loop we are on
let total = 0; //Used to add up all of the even numbers
let mean = 0; //Used to calcate the mean of all even numbers
do {
i = i + 1; //Keep track of what loop we are on
num = num + 2; //Used to calcate the even number
arr.push(num); //Push the num into a array
total = total + arr[i]; //Calcate the total of the array
mean = total / i; //Calcate the mean
}
while (num != loop);
//Output the result
console.log(mean);
