What is the difference between ODBC and ADO?
What is the difference between ODBC and ADO? ODBC is an open interface, which can be used by any application to communicate with any database system, while ADO is a wrapper around OLE DB (which is the successor to ODBC). If the database does not support OLE (non-OLE environments) then ODBC is the best choice.
Is ADO faster than ODBC?
There is no speed advantage inherent to ODBC vs ADO.NET, but there is some speed loss for such bridged solutions, due to the extra layer of API translation.
