Data is essential if you're going to be doing any database work in your application. You still need to explicitly import the data provider that you're going to use.

The second two variables are just for convenience and specify the server that you're going to connect to, and the database within that server. NET terms, these are known as the data source and catalog. For the code to run on your machine, you'll need to change the dataSource variable to match the name of the machine that your database is on. In my writing cave (really, it has no windows and only a single lightbulb), the machine is called Saratoga and since I'm using MSDE as the database server, I need to suffIx the machine name with "\ VSTE".

Actually establishing the database connection requires a second operation.
