First you must pick a database. This is just a few, most of them are free:
Microsoft SQL: http://msdn.microsoft.com/en-us/library/aa936940%28v=sql.80%29.aspx
ODBC (Any): http://www.easysoft.com/developer/languages/c/odbc_tutorial.html
Then you need to link your program to it. Pick your compiler and find out how to do it.
