DAO came first, and was bundled with Microsoft Access, but it can be used to access other databases as well, but RDO is a better set of objects for accessing other types of remote databases. Both have been superceded by ADO (or ADODB) which are thread-safe and provide more functionality than the earlier DAO and RDO, including disconnected record-sets.
