Accessing a Web Database using a Local Application

We're currently developing a desktop Application using C# and we'eve created a Local Database using MYSql.



Now are trying to create an desktop application that can access a web database but we don't know what to do.

1) Is it possible to create a desktop application that can do that just by using C#?

2) How can we convert or connect a local database to the internet?

3) what do language do we need to learn?
