Deploying Windows forms application with database

hi i'm making a database program that using sql server database, i made it using visual studio 2010 and sql server management studio 2008.
i want to deploy my program and make it an installer.
but i'm wondering how can i make the installer with the database included within it, so when i install for the end user they doesn't need to own the sql server?
because the connection string that i made is connected with my own sql server on my own computer. So how can i build it. is using mdf files or what? i've search a lot of articles but it didn't make understand how. is there any easy way to do it?

thanks
