Answer: False 
Explanation: 
This means that the mappings between the two schemas may be specified in either one of these languages.In most relational DBMSs today, there is no specific language that performs the role of SDL. Instead, the internal schema is specified by a combination of functions, parameters, and specifications related to storage. These permit the DBA staff to control indexing choices and mapping of data to storage
 
        
             
        
        
        
Answer:
#include <iostream>
using namespace std;
int * reverse(int a[],int n)//function to reverse the array.
{
    int i;
    for(i=0;i<n/2;i++)
    {
        int temp=a[i];
        a[i]=a[n-i-1];
        a[n-i-1]=temp;
    }
    return a;//return pointer to the array.
}
int main() {
    int array[50],* arr,N;//declaring three variables.
    cin>>N;//taking input of size..
    if(N>50||N<0)//if size greater than 50 or less than 0 then terminating the program..
    return 0;
    for(int i=0;i<N;i++)
    {
        cin>>array[i];//prompting array elements..
    }
    arr=reverse(array,N);//function call.
    for(int i=0;i<N;i++)
    cout<<arr[i]<<endl;//printing reversed array..
    cout<<endl;
 return 0;
}

Explanation:
I have created a function reverse which reverses the array and returns pointer to an array.I have also considered edge cases where the function terminates if the value of the N(size) is greater than 50 or less than 0.

Answer:
Data is stored in tables, where each row is an item in a collection, and each column represents a particular attribute of the items. Well-designed relational databases conventionally follow third normal form (3NF), in which no data is duplicated in the system. ... With a homogenous data set, it is highly space efficient
