Cost of Data Complexity = (((Number of Data Elements) * Complexity of the Data Storage Technology) * Labor Units))
Number of Data Elements being the number of semantics you?re tracking in your domain, new or derived.
Complexity of the Data Storage Technology, expressed as a percentage between 0 and 1 (0% to 100%). For instance, Relational is a .3, Object-Oriented is a .6, and ISAM is a .8.
So, at $100 a labor unit, or the amount of money it takes to understand and refine one data element, we could have:
Cost of Data Complexity = (((3,000) * .5) * $100)
Or, Cost of Data Complexity = $150,000 USD Or, the amount of money needed to both understand and refine the data so it fits into your SOA, which is a small part of the overall project by the way.

I can't speak for David - but I can promise you, this is not how we estimate SOA efforts. I'm not even sure what David is attempting to estimate. This post has me so confused... I'd recommend deleting that post - real soon.
