ActiveX Data Objects (ADO) enables you to write a client application to access and manipulate data in a data source through a provider. ADO is ideally suited to consume data exposed by OLE DB providers, such as those written with the Microsoft OLE DB Simple Provider Toolkit. ADO’s primary benefits are ease of use, high speed, low memory overhead, and a small disk footprint.
By using the Toolkit with ADO, you build a foundation for implementing flexible data access strategies at a higher level. For example, you can combine ADO's ease of application programmability with the Simple Provider Toolkit's ease of developing providers to quickly build end-to-end, single, or multi-tiered applications that address your corporate, intranet, Internet, or enterprise-wide data access needs.
For more information about ADO, including a detailed description of the object model, ADO properties and methods, and complete code samples, refer to the ADO help file supplied with the DA SDK.
