Languages required for creating a database for a website

Question

Which languages should I learn to create a database like the database of Facebook or YouTube and other websites?

Answer 1

ASHRAF not sure what you are asking....
If you are curious about creating a database and add/query content you can look up some free relational db such as postgresql, and learn sql language.
If you are asking about creating a website around it as well, there are multiple solutions, look up 'web application' , this will give you examples of architecture and languages and frameworks you can use.
