Failure in a database environment is more serious then a non data base because if you lose important information you may not get it back and failure in a nondatabase environment the problem may be more easier to solve

Answer:

Failures in database environments can occur due to hardware failures, power failures and software/programming error.

Of these three errors, the non-database environment can survive the hardware failure due to recovery processes and the Software/programming error.

Explanation:

Databases are quite fragile when they hit a hardware failure if you try to recover them (Most of them have raw files that can only be read by certain types of Database Management Softwares) this does not exist in the Non-Database Scenario as most of these records are kept in files.

Software failures can occur when a wrong query is used to retrieve data from a DBMS. This can be frustrating except the user gets the right query.

Answer:

Following are the correct python code to this question:

n1 = float(input('Input first number: '))#input first number  

n2 = float(input('Input second number: '))#input second number  

n3 = float(input('Input third number: '))#input third number  

n4 = float(input('Input fourth number: '))#input fourth number  

average = (n1+n2+n3+n4)/4 #calculate input number average

product = n1*n2*n3*n4 # calculate input number product

print('product: {:.0f}  average: {:.0f}'.format(round(product),round(average))) #print product and average using round function

print('product: {:.3f}  average: {:.3f}'.format(product,average)) #print product and average value

Output:

Please find the attachment.

Explanation:

The description of the above python code can be defined as follows:

  • In the above python program four variable "n1, n2, n3, and n4" is defined, in which we take input from the user end, and in these user inputs we use the float method, that converts all the input value in to float value.
  • In the next step, two variable average and product are defined, that calculate all input numbers product, average, and hold value in its variable.
  • In the last line, the print method is used, which prints its variable value by using a round and format method.
