<P>

Although DNA is associated quite closely with Microsoft, 
no one actually 'owns' the architecture. If you use it, 
there are no payments, no penalties, and definitely no 
right or wrong ways to implement it. It's a high level 
idea; there are no coding practices, special notations 
or even restrictions on the technologies to use. 

<P>

However, this is not to say that Microsoft does not gain 
a huge advantage if you adopt the architecture.  

<P>

The DNA 
approach to building applications is a pseudo 
technical-come-marketing idea generated from Microsoft that is both 
application development architecture and medium for selling 
application developers more products. It is an approach that 
delivers in stages, often expensive stages, 

<P>

The reality of the model is that it fits neatly into a 
range of Microsoft technologies, which is in part, by 
design. Thus, it is common that if you adopt the 
architectural model, you'll also adopt quite a few 
non-free Microsoft products in the process.  That is 
because the Microsoft products all work in support 
of the architecture. 

<P>

However, in defense of Mirosoft, when we say that the Microsoft 
suite of technologies happen to slot nicely into the DNA 
architecture, what we really mean is that the products have 
been engineered for the architectural solution.  The products 
do work fairly well in helping developers implement the 
architecture and the architecture does help developers 
write applications! What's more, you can use any products,
even non-Microsoft ones, in a DNA architected application.
It just may be a little more inconvenient!

<P>

Microsoft DNA encompasses all, and more, of the technologies 
and practices that we shall cover in this tutorial. If you 
already work and develop solutions using databases, middleware, 
connectivity products and services from Microsoft then you 
are already using some portions of the DNA technology 
structure. The only remaining question is whether you 
are using the methodology as well.  Using the technologies 
without the methodology is acceptable, but you won't reap 
the full benefits the technologies and architecture have 
to offer.  

<P>

In other words, you can write ASP applications that do not
leverage the DNA.  And they will work just fine.

<P>

However, if you do so, you gain none of the
special benefits that ASP has to offer over other similar
solutions such as CGI or Servlets.

<P>

As a result, in this tutorial, we'll be paying close attention to not just 
the tools of ASP, but how they fit into the greater DNA 
architecture.

<P>
