Explanation: Normalization is the process through which the reduction in the redundancy of data can happen.It makes the redundant in control which decrease the issue of the data integrity that appears in the good and bad database tables.

In good tables it functions for the storing of the objects in the relational database which is a difficult task and thus helps in the linking of the tables of databases.The same information level can be maintained for the different places.

egoroff_w [7]

Answer:

Explanation:

The following code is written in Python. It creates a class that takes in one ArrayList parameter and loops through it and calls two functions that check if the numbers are Perfect, Odd, or Even. Then it goes counting each and printing the final results to the screen.

class NumberAnalyzer:

   def __init__(self, myArray):

       perfect = 0

       odd = 0

       even = 0

       for element in myArray:

           if self.isPerfect(element) == True:

               perfect += 1

           else:

               if self.isEven(element) == True:

                   even += 1

               else:

                   odd += 1

       print("# of Perfect elements: " + str(perfect))

       print("# of Even elements: " + str(even))

       print("# of Odd elements: " + str(odd))

   def isPerfect(self, number):

       sum = 1

       i = 2

       while i * i <= number:

           if number % i == 0:

               sum = sum + i + number / i

           i += 1

       if number == sum:

           return True

       else:

           return False

   def isEven(self, number):

       if (number % 2) == 0:

           return True

       else:

           return False
