So, basically, I am a total n00b. I have never tried connecting a database to a project before.

So, I am using C# for this simulator me and my friends are coding and we want to add a database to it. We have created it using Visual Studio 2010 but we have no idea what to do afterwards. Do we create an extra class to hold all the database stuff and then call its methods from whichever class we want?

The database is a .mdf, in case it's important.

I'm using DAO pattern. Java example: Core J2EE Patterns - Data Access Object.
You can implement it in C#.

use LINQ.

create a dbml file in visual studio.
open it and click the Server explorer Link in there. it will open a panel on left side.
Add a new connection to your database.
Drag all the objects/tables to your dbml file
save the file

and you are almost done.
db is connected, now you need to query it
if you need the connection string, its in your web.config already when you save the dbml file.
