<P>

Avoiding the obvious medical connotations, what is DNA and
what does it have to do with ASP (Active Server Pages)? 

<P>

Well, DNA (Distributed interNet Architecture) 
is an abstract methodology. It is a way of designing 
applications with growth, deployment, and load taken as  
major considerations. More specifically, DNA is a software 
application engineering design pattern. It is a solution to 
a set of common problems that are described in a generic, 
abstracted enough manner as to enable the application of 
the pattern in a wide variety of situations.

<P>

In other words, DNA is just a way to think about writing 
applications.  It is a metaphor, as you will, that can help 
you understand and solve complex problems in simple terms.  

<P>

Think of the DNA architecture not as the car, or the 
assembly line, but as the abstract idea of mass 
production.  It is a process...a way.

<P>

However, DNA is more than just an abstract pattern.  
It is also a very tangible set of technologies.  Specifically 
it is a set of (traditionally) Microsoft technologies that 
together help developers implement the DNA architecture within 
their applications.

<P>

So how does DNA relate to ASP?

<P>

Well, as it turns out, from a web developer's perspective, it
is through ASP that the set of technologies implementing a
DNA solution are glued together and distributed over the web.
