Microsoft ADO Programmer's Reference

Microsoft® ActiveX® Data Objects (ADO) enable you to write an application to access and manipulate data in a database server through an OLE DB provider. Its primary benefits are ease of use, high speed, low memory overhead, and a small disk footprint. ADO supports key features for building client/server and Web-based applications.

ADO also features Remote Data Service (RDS), by which you can move data from a server to a client application or Web page, manipulate the data on the client, and return updates to the server in a single round trip. Previously released as Microsoft Remote Data Service 1.5, RDS has combined with the ADO programming model to simplify client-side data remoting.
