I remember from my CR 2008 exams that we only explicitly spoke about ODBC connections. However, it's just as easy to setup an OLE DB connection. In fact, if I use an OLE DB connection on Crystal Reports Server, then no ODBC Data Source needs to be created on the server side. Seems easier to me.
Have I missed something? Why would I use an ODBC connection ever again as OLE DB is just as easy? According to some, OLE DB is faster as well.
Have a nice day,
