Windows DNA is essentially a 'blueprint' that enables corporate Windows DNA is essentially a 'blueprint' that enables corporate developers and independent software vendors (ISVs) to design and build developers and independent software vendors (ISVs) to design and build distributed business applications using technologies.distributed business applications using technologies.

The following principles guided microsoft in developing the windows DNA architecture.

Web computing without compromise

Interoperability

True integration

Faster time to market

Reduced complexity

Windows DNA Architecture is a dynamic set of technologies that you can use to build Web applications.

Component Object Model (COM) Dynamic Hypertext Markup Language (DHTML). Windows Script Components XML: Extensible Markup Language (XML). Active Directory Service Interfaces and IIS

The application developer today must develop a user interface that is distributable, available on Windows and non-Windows platforms, and supports a wide range of client environments, from handheld wireless devices to high-end workstations.

Windows DNA permits the developer to choose the appropriate Windows components and Internet technologies to support the richest possible interface and range of client environments, from handheld wireless devices to high-end workstations

DNA helps to design and build multi-tier client/server applications.

DNA application are Platform independent.

DNA applications provide full transactional processing support.

DNA can be used to create applications that are fault tolerant.

DNA is ideal for distributed applications.

Providing a comprehensive and integrated platform for distributed applications.

Faster and easier to build distributed applications by providing a pervasive component model, extensive prebuilt application services.

Provides wide choice of programming language and tools support.
