Answer:

In DBMS, an index is a physical structure that stores the values for a specific column in a table. An index can be used to extract specific information from data and access records within a table more quickly without having to scan the whole table.

An Index can be made up of one or more columns of a table and each index maintains a list of values within that field that are sorted in ascending or descending order. Indexes cannot be seen by the users, but they are just used to speed up the queries and improve the performance of a database application

Explanation:

The use of the inheritance to have a structure inherit attributes and methods of classes above it.

One of the key milestones in the period in which the object-relational model was created was the creation of a data
model that closely represented the real world. In this approach, objects were created in which both data and its
relationships were all contained in one place. These data models were becoming a norm to be stored on the web. They
also incorporated support for star schemas within data warehouses. Objects that had similar characteristics were
grouped into classes, where they had a shared structure of attributes and behaviors.

One of the milestones during this period was the use of Unified Modeling Language to represent the data models. The correct option is C.

Using object-oriented programming languages, object-relational mapping is a programming technique used in computer science to convert data between type systems. As a result, the programming language becomes a "virtual object database" that may be used.

One of the significant achievements throughout the development of the object relational model was the development of a data model that accurately reflected the real world.

Using this method, objects were constructed that contained all of the data and the relationships between it. The storage of these data models online was starting to become standard.

Additionally, they included support for star schemas in data warehouses. Classes would be composed of comparable structures with similar shared characteristics and actions.

Thus, the correct option is C.

The Python program to calculate the average of all even integers between 1 and 10000 is given below.

We have,

The Python program to calculate the average of all even integers between 1 and 10000:

def main():

   even_sum = 0

   count = 0

   for num in range(2, 10001, 2):  # Starting from 2 and incrementing by 2 (only even numbers)

       even_sum += num

       count += 1

   if count > 0:

       average = even_sum / count

       print("Average of even integers between 1 and 10000:", average)

   else:

       print("No even integers between 1 and 10000.")

if __name__ == "__main__":

   main()

In this program, we define a function main() that runs the main logic.

We initialize even_sum to store the sum of even numbers and count to keep track of how many even numbers we encounter.

The for loop iterates through even numbers between 2 and 10000 (using the range() function with a step of 2).

Inside the loop, it adds each even number to even_sum and increments the count.

Thus,

The Python program to calculate the average of all even integers between 1 and 10000 is given above.

Explanation:

The required function in python is written as follows :

user_num = int(input())

#takes an input value and convert to an integer value.

while user_num >= 1 :

#While loops is conditioned to run if user_num is ≥ 1

user_ num = user_num / 2

#divide user_num by 2 and store the result as user_num

print(user_num)

#print user_num

The while loop condition does most of the work here, The while loops is conditioned to run the divison of user_num if the value of user_num is greater than or equal to 1 ; if user_num is lesser than 1, the loop terminates.

Answer:

user_num = float(input("Enter a number: "))

while(user_num > 1):

user_num = user_num / 2

print(user_num)

Explanation:

Line 1:

Use built-in function input() to prompt user input a number and assign it to the variable user_num.

Since the default data type of the user input is a string, we need to convert it into float data type before assigning it to user_num. We can do the data type conversion by enclosing the user input into the built-in function float().

Line 3:

Create a while loop by setting condition while user_num bigger than 1, the line 4 & 5 should keep running.

Line 4:

Divide user_num by 2 and assign the division result back to the user_num.
