If you have the mdf and ldf files and they are not corrupt you can do an "attach" to connect the database to SQL Server. If the files are corrupt and you do not have a good backup, there is not much you can do. There are some companies out there that say they can recover the data. So, I would look them up on the Internet to see what they can do for you.
