Hi Joe.
  Viewing things from a different perspective, I would view this as a 
negative 
aspect of the programming language/applictaion environment. 

  So, can you explain a bit about how this model reacts to changes in the
database and what schemes are typically used to minimize such 
changes or make them tranparent?

  Additional tables, changes in columns type, sizes usages?
  Fields that are not clean and and databases that are not designed well
One example I've seen is where char fields represent different scalar data 

(even different units) depending on the values of other fields. The units 
were
in yet another field in a psuedo-standard way because of the age and 
growth
characteristics of the database.

  How do you address those things in general?
