Microsoft Windows Distributed interNet Application Architecture

  • Article

Microsoft developed the Windows Distributed interNet Application Architecture (DNA) as a way to fully integrate the Web with the n-tier model of development. Windows DNA defines a framework for delivering solutions that meet the demanding requirements of corporate computing, the Internet, intranets, and global electronic commerce, while reducing overall development and deployment costs.

Windows DNA architecture employs standard Windows-based services to address the requirements of each tier in the multitiered solution: user interface and navigation, business logic, and data storage. The services used in Windows DNA, which are integrated through the Component Object Model (COM), include:

  • Dynamic HTML (DHTML)
  • Active Server Pages (ASP)
  • COM components
  • Component Services
  • Active Directory Services
  • Windows security services
  • Microsoft Message Queuing
  • Microsoft Data Access Components

Microsoft built Windows DNA using open protocols and public interfaces, making it easy for organizations to integrate third-party products. In addition, by supporting industry-defined standards for Internet computing, Windows DNA makes it easier for developers to respond to technology changes. Some of the technologies involved in Windows DNA are illustrated in the following diagram.
