The previous section discussed the benefits of providing database access solutions on the Web. This section discusses how you can develop these solutions using Microsoft data access technologies.
Universal Data Access is Microsoft’s initiative for providing high-performance access to all types of information (including relational and nonrelational data) across an organization, from the desktop to the enterprise, using practically any tool or language.
In a parallel effort with the Microsoft® Windows® Distributed interNet Applications (Windows DNA) architecture, the Universal Data Access initiative is a platform, application, and tools strategy that defines and delivers standards and technologies essential for application development.
MDAC is comprised of the data access technologies that enable Universal Data Access: ODBC, OLE DB, and Microsoft® ActiveX® Data Objects (ADO). The figure below shows how these data access components interact. For the latest information and current releases of MDAC see http://www.microsoft.com/data.
The next few sections describe each of the MDAC technologies. Most of your Web applications will use ADO, which is described in detail later.
