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.

devlian [24]

Answer:

// here is code in java.

import java.util.*;

// class definition

class Main

{

// method that return total fare

public static double fare(double dis)

{

// calculate the total fare

double tot_fare=(4+((dis*1000)/140)*0.25);

return the fare

return tot_fare;

}

//driver method

public static void main (String[] args) throws java.lang.Exception

{

try{

// scanner object to read input string

Scanner s=new Scanner(System.in);

// variable

double dis;

System.out.print("please enter the distance in KM: ");

//read the number

dis=s.nextDouble();

// call the function with "dis" parameter

double ride_fare=fare(dis);

// print the total fare

System.out.println("total fare is: "+ride_fare);

}catch(Exception ex){

return;}

}

Explanation:

Read the distance from user with the help of scanner class.Call the function with parameter "dis".Here it will calculate the total fare as (4+((dis*1000)/140)*0.25). Here base fare is $4 and $0.25 for every 140 meter.Then function will return the total fare.
