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:
C. Mean
Explanation:
Mean = (∑
)/N
Median = central values when data is sorted
Mode = most repeated value
Standard deviation = 
In standard deviation, formula you may see that deviation is being calculated from the mean (central location). But here we take square of the value before adding all of them.
But if we just take
, it would be equal to zero.
<u>EXAMPLE</u>
Take 4, 9, 5 as data
mean = (4+9+5)/3 = 18/3 = 6
sum of deviations from mean = (4-6)+(9-6)+(5-6) = (-2)+(3)+(-1) = 0

Answer:
#include <iostream>
#include <cstring>
using namespace std;
void replacePeriod(char* phrase) {
int i = 0;
while(*(phrase + i) != '\0')
{
if(*(phrase + i) == '.')
*(phrase + i) = '!';
i++;
}
}
int main() {
const int STRING_SIZE = 50;
char sentence[STRING_SIZE];
strcpy(sentence, "Hello. I'm Miley. Nice to meet you.");
replacePeriod(sentence);
cout << "Updated sentence: " << endl;
cout << sentence << endl;
return 0;
}
Explanation:
- Create a function called replacePeriod that takes a pointer of type char as a parameter.
- Loop through the end of phrase, check if phrase has a period and then replace it with a sign of exclamation.
- Inside the main function, define the sentence and pass it as an argument to the replacePeriod function.
- Finally display the updated sentence.
