What's your ideology for how applications should be created?

Hi Folks,

"An ideology is ... a conceptual framework with the way people deal with reality." [Alan Greenspan]

What's your ideology for how applications should be created?

I oftentimes see parts and pieces of a conceptual framework for application design, but rarely do I see a complete framework. 

What appeals to me about Michael Kay's article[1] is that it is a complete conceptual framework (ideology), expressed by an extraordinarily bright individual, possessing a wealth of experience. (much like Alan Greenspan)

Here is the Michael Kay ideology, in a nutshell:

Create workflow-based applications. Design XML documents to mimic documents in the physical world. Store the XML documents centrally, in an XML database. Pass around URLs to the documents. Use an all-XML solution; avoid using imperative languages. 

What's your ideology for how applications should be created?

P.S. Michael Kay, I hope that I have accurately portrayed your ideology. Please correct any errors.
