INTRODUCTION

Understanding The Microsoft Windows DNA
Architecture- 

• Windows DNA specifies how to develop robust,
  scalable, distributed applications using the
  Windows platform.
• Windows DNA is essentially a 'blueprint' that
  enables corporate developers and independent
  software vendors (ISVs) to design and build
  distributed business applications using
  technologies.

2. Guiding Principles of Windows DNA

• The following principles guided microsoft in
  developing the windows DNA architecture.
• Web computing without compromise
• Interoperability
• True integration
• Faster time to market
• Reduced complexity

  Development Technologies

• 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

• Central Database

• Microsoft's web server software product

• Internet Explorer 4.0

• Dynamic HTML

• Cooperating Components

5.Client Environments and Presentation Tier

• 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

8.Features of Windows DNA

• 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.

9.Conclusion

• 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.
