Answer:

An internal schema                                                            

Explanation:

  • The internal schema refers to the physical storage structure of database.
  • It refers to the lowest level of abstraction.
  • This is also called physical schema.
  • It contains multiple instances of multiple internal records.
  • It provides information about the representation of the whole database that what data is stored in DB and in what form e.g the data is stored in the records form on the disk.
  • This schema gives detailed description of internal model which involves storage structure of the database, representation and classification of stored data. This format of data is only understandable by the Database management system.

wel

Answer:

The code example is given below with explanation in c++ language.

Explanation:

Comments will explain what's going on in the code. Below code is already compiled and tested.

#include <time.h>

#include <iostream>

#include <sstream>

using namespace std;

int main(void)

{

//defining start and end time variable

// which will be used to break the infinte loop

   time_t endwait;

   time_t start = time(NULL);

   time_t seconds = 3; // end loop after this time has elapsed

cout<<"Input your number :";

long userNum;

cin>> userNum;

// initializing end time by adding seconds with start time

   endwait = start + seconds;

   // defining outputString which will concatenate all the  

   // divisible numbers in loop

string outputString="";

// bool isCompleted will use to check whether our  

// loop breaks successfully or time is expired.

bool isCompleted=true;

// iterate loop until it comes to 1. as in loop

// the program already displayed the 1 value.

   while (userNum>1)

   {  

  // checking start and end time comparison to  

  // break the infinite loop after some seconds

    if(start >= endwait){

     cout<< "Program end never reached.";

     isCompleted=false;

     break;

 }

 

    userNum=userNum/2;

   // defining stringstream to convert from long to string

    stringstream longToString;

    longToString<<userNum;

  // concatenating all the values

    outputString = outputString + longToString.str()+" ";

   // re initializing the start time with current time.

       start = time(NULL);

   }

   

  // check if while loop breaks successfully then print the

   // series of numbers here.

   if(isCompleted) {

    cout << outputString;

}

   return 0;

}
