D-Tier Development

Coining a buzzword (if it hasn’t been coined already), n-tier development is in the past.  D-Tier development is where we’re moving to.  The “D” can mean either “distributed” or, more in line with what I’m thinking, the ‘d’ in the word “multidimensional”, or simply “Dimensional.”

Why?  Because in an n-tier system, we still think of it fairly linearly: back-end, middle tier, and client-side, as one example.  OK, each tier may be implemented on a physically separate system, but doesn’t need to be.

A D-Tier implementation consists of autonomous entities distributed across a variety of physical and virtual platforms and interconnected in multidimensional ways.

Another aspect of D-Tier development is the highly “dynamic” nature of a distributed, autonomous entity architecture.  Entities can come and go, providing a continually changing environment of behavior that is tailored to the user’s needs.
