3. Data access technology is constantly evolving, and each of these
three interfaces represents a different stage of development for
Data Access Technology :
• ActiveX Data Objects (ADO)
• Remote Data Objects (RDO)
• Data Access Objects (DAO)
The latest is ADO. Its features are simpler — yet more flexible —
