An online company wants to conduct real-time sentiment analysis about its products from its social media channels using SQL.
iogann1982 [59]

Answer:

An online company wants to conduct real-time sentiment analysis about its products from its social media channels using SQL. The solution which has lowest cost and operational burden is as follow:

B. Configure the input stream using Amazon Kinesis Data Streams. Use Amazon Kinesis Data Analytics to write SQL queries against the stream.

Explanation:

  • The option A is not correct as this solution doesn't have lowest cost and operational burden as set up a streaming data ingestion application on Amazon EC2 and connect it to a Hadoop cluster for data processing will have more cost and operational burden.
  • The lowest cost and operational burden solution is that we configure input stream using Amazon Kinesis Data Streams. We can use Amazon Kinesis Data Analytics to write SQL queries against the stream.
  • The option c and d are also more pricey in terms of cost and operational burden as compared to Amazon Kinesis Data stream and analytics.

(Count positive and negative numbers and compute the average of numbers) Write a program that reads an unspecified number of int
Papessa [141]

Answer:

Explanation:

Sorry it  is in Java, though you can covert it using converter

public class Exercise {

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 int positives = 0;  // Count the number of positive numbers

 int negatives = 0;  // Count the number of negative numbers

 int count = 0;   // Count all numbers

 double total = 0;  // Accumulate a totol

 // Promopt the user to enter an integer or 0 to exit

 System.out.print("Enter an integer, the input ends if it is 0: ");

 int number = input.nextInt();

 if (number == 0) { // Test for sentinel value

  System.out.println("No numbers are entered except 0");

  System.exit(1);

 }

 while (number != 0) {// Test for sentinel value

  if (number > 0)

   positives++; // Increase positives

  else

   negatives++; // Increase negatives

  total += number; // Accumulate total

  count++;    // Increase the count

  number = input.nextInt();

 }

 // Calculate the average

 double average = total / count;

 // Display results

 System.out.println(

  "The number of positive is " + positives +

  "\nThe number of negatives is " + negatives +

  "\nThe total is total " + total +

  "\nThe average is " + average);

}

}
