ODBC is a standard way of accessing different databases. You can program it directly using API calls. This will be the fastest of all methods, but will require more development time and debugging.

DAO (Data Access Objects) is the MS Jet dataabse engine. When aqccessing ORACLE, it will sit on top of ODBC which talks to the native ORACLE libraries. This will probably be the least efficient

RDO (Remote Data Objects) was designed for accessing ORACLE and SQL server. It is a thin layer on top of ODBC.

ADO (ActiveX Data Objects) is the newest method. It again sites on top of ODBC or the new OLEDB. It is best used with OLEDB MS's "replacement" for ODBC. It will be the best method to use if you are doing a lot of web based applications.

Running against SQL server I found that ADO is alot slower using ODBC than when using OLEDB. Microsoft has released an OLEDB provider for ORACLE.

Without the web access I would use RDO. With the web access I would use ADO with an OLDB provider for ORACLE.
