Probably this is the lamest question ><
I am developing an ASP.net web app with SQL Server database. When the client asked me to develop the system, he provided a file for the database.
I thought the file was a dumpfile (if you familiar with oracle or mysql, you can replicate database with dumpfile, which is basically bunch of queries inside a text file).
To my horror, plus with my noobity in SQL Server, I found out that it was NOT a dumpfile. The file is rename to .bak which is not really the correct extension for SQL Server. I tried to rename it to .mdf, but no luck.
What should I do? The client is out for vacation on some island and cannot be contacted at the moment?
This is backup file, you need to restore database from backup.
