It uses primary keys and foreign keys as a means to provide efficient access to data and is supported directly in the database rather than maintained in the application code.
Explanation: Relational databases use an expressive query language, make efficient use of indexes within the database, ensure strong consistency, and fit well within an enterprise management system. Non-relational databases have a flexible data model, have high scalability, and performance, and have always-on global deployments.
Answer:
Check the explanation
Explanation:
#include <iostream>
using namespace std;
void hex2dec(string hex_num){
int n = 0;
//Loop through all characters in string
for(int i=0;i<hex_num.size();i++){
//take ith character
char c = hex_num[i];
//Check if c is digit
if(c>='0' && c<='9'){
n = 16*n + (c-48);
}
//Convert c to decimal
else{
n = 16*n + (c-55);
}
}
cout<<hex_num<<" : "<<n<<endl;
}
int main()
{
hex2dec("EF10");
hex2dec("AA");
return 0;
}
