Answer / Sudhir Kumar Keshari

ADO (ActiveX Data Objects) is a programming interface that allows you to access and manipulate data stored in various data sources, such as databases or XML files. It was introduced by Microsoft for use with COM-based applications and relies on the OLE DB technology. RDO (Remote Data Objects), on the other hand, is an extension of ADO that provides a more object-oriented approach to working with data, allowing you to work directly with database tables as if they were in-memory objects.
