How do I access the Database from the Server Explorer in Visual Studio?

[flexluthor]

I just started Visual Studio and I followed a video that created a local database and connected it to Server Explorer in Visual Studio, the steps I did were:

1. Right click my project, choose Add -> New Item -> Service-based Database

2. Went to the Server Explorer on the left, right clicked on Data Connections, choose Add Connection, selected the database that I created, tested the connection and it passed then pressed Ok

3. Populated my Database with three tables and added ten rows of data

 

Now I don't know exactly how would my form have access to the database I created, I have a small experience with databases as I've studied web development for a month and I remember I made a variable to store the connection to the server, database, username, password then used that variable after every query I made.

Oh okay nevermind, I just had to create a dataset from the database and drag it onto the form.
