MDAC 2.5 SDK - OLE DB Providers
OSP Toolkit
Microsoft® 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. The primary benefits of ADO are ease of use, high speed, low memory overhead, and a small disk footprint.
By using the OSP Toolkit with ADO, you build a foundation for implementing flexible data access strategies at a higher level. For example, you can combine the ease of application programmability of ADO with the OSP Toolkit's ease of developing providers and quickly build end-to-end, single, or multitiered applications that address your corporate, intranet, Internet, or enterprisewide 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 MDAC SDK.
