Connecting Mfc application to remote Sql server

I've been working in a MFC application Which requires a database connectivity... I've Worked with C# and database, VB and database where i used Connection string IP Address, User Id,Password to access database. But I've been trying to find similar way to establish connection between My MFC application and remote Sql server.. But I couldn't find any.. Some articles say Use ODBC some say DBO... I'm totally Confused... Please HELP Where do i start?? Can Any one get me simple example links...?? Which one is better ODBC o DBO??
