Microsoft states that remote data objects and data access objects are outdated methods of data access interface in Visual Basic.

Due to the complexity of OLE DB, it should not be accessed directly. ADO functions as the interface allowing full use of OLE DB. ADO uses many commands similar to RDO and DAO and the OLE automation interface to facilitate and speed up retraining by individuals accustomed to the older data access interface systems. While ADO has a relatively simplistic interface, it offers a greater and more nuanced interface with OLE DB. Microsoft strongly suggests upgrading from RDO to ADO.
