Which of the following criteria was a key milestone for the object-relational model created in the mid-1980s?
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.
What is object-relational model?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.

Write a while loop that prints user_num divided by 2 until user_num is less than 1
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.
Line 5:
Display updated value of user_num using built-in function print()

The variable customer_category is a string that is one of these 4 values.
0 for "None"
5 for "Bronze"
10 for "Silver"
20 for "Gold"
Your colleague wrote the following program (Program C). Does the program that he/she wrote have the correct logic to assign the correct discount for each of the 4 valid values of customer_category?
Program C:
if customer_category == "None":
discount = 0
if customer_category == "Bronze":
discount = 5
if customer_category == "Silver":
discount = 10
if customer_category == "Gold":
discount = 20
Yes, the written program has the correct logic to assign the correct discount for each of the 4 valid values of customer_category
What is a Program?This refers to the sequence of instructions that are keyed into a computer to execute user-specific commands.
Hence, we can see that based on the variable customer_category that has a string that is one of these 4 values:
0 for "None"
5 for "Bronze"
10 for "Silver"
20 for "Gold"

Modify your code to use an enhanced for loop.
ty in advance
See below for the modified program in Java
How to modify the program?The for loop statements in the program are:
for (int i = 0; i < arr.length; i++) { arr[i] = rd.nextInt(1000); }for (int i = 0; i < arr.length; i++) { System.out.println(arr[i]); }To use the enhanced for loop, we make use of the for each statement.
This syntax of the enhanced for loop is:
for(int elem : elems)
Where elem is an integer variable and elems is an array or arrayList
So, we have the following modifications:
i = 0; for (int num : arr){ arr[i] = rd.nextInt(1000); i++;}for (int num : arr) { System.out.println(num); }Hence, the modified program in Java is:
class Main {
static int[] createRandomArray(int nrElements) {
Random rd = new Random();
int[] arr = new int[nrElements];
int i = 0;
for (int num : arr){
arr[i] = rd.nextInt(1000);
i++;
}
return arr;
}
static void printArray(int[] arr) {
for (int num : arr) {
