It looks superficially similar to DAO and RDO but offers vastly greater capabilities under the hood and is thoroughly geared to the needs of client/server systems. Microsoft has stated that they will put no effort into further enhancements of RDO, DAO, and ODBC (although they are committed to supporting ODBC for the long haul), so ADO sounds like the COM interface of the future. Here are some of the enhancements offered:

  • ADO exposes objects that wrap up the data definition language of a data store, meaning you can write code to create and modify tables and indexes, which works against a variety of underlying databases, even nonrelational ones.
