How to apply a SQL file to a website?

I know how to setup the database(import the SQL file to php myadmin)

But after I import the files what do I do (note- This is for a new site that has no files, do I need to create an index file or what) I am new to mySQL not a total noob but a noob because I have no experience... who ever can help I would appreciate it so much..

Thanks

... what type of database is it? inserting only sql file into a db might populate the db but it won't create the site.
