You will need to put database files in a server.
You will need to program an interface for your users.
so that users can access database from anywhere in the world as long as they have internet connections.
For example: DH supports PHP programming and MySQL database. Usually we build a MySQL database in our database server and build web interface using PHP to manipulate data in database.
Btw, what is your database? Is it a MySQL, Access, or other file?
