Microsoft Data Access Components

What is Microsoft Data Access Components?

The Microsoft Data Access Components, abbreviated to MDAC, DAC, or Windows DAC, is a set of instructions or programs that enable – as evinced by the name – the access and manipulation of databases and the data contained therein. Such a set of software is called a library, and the Microsoft DAC is a collection of these components that are further subdivided into further categories, depending on their purpose and what they do. The Data Access Components are an integral part of the Windows operating system family, and although a Windows Update automatically updates this as well (if there are updates available), they can also be downloaded freely from the Windows website if you are using a Windows-based computer and have a valid license. A new version installed this way overwrites the old one, essentially updating it.

The DAC is a key component of Universal Data Access, and used for client and server relationships so they can make sense of the data between them, especially through a network (like the Internet) or a LAN, or to integrate the information taken from other sources, like a database (for example an SQL). The DAC includes ActiveX Data Objects, OLE DB, and Open Database Connectivity.
