If your data is allready in a SQL server format, it is easy:
Hust copy the data on disk & use sp_attach_db
EXECUTE sp_attach_db @dbname = N'test_db',
@filename1 = N'c:\program files\microsoft sql server\mssql\data\test_db.mdf',
@filename2 = N'c:\program files\microsoft sql server\mssql\data\test_db_log.ldf'
GO
