Need to question/challenge you here on "dynamaticity" (certainly a  
word I've never seen before)?    (04)

If I'm interpreting it right it appears to mean that information in a  
database tends to be static or used for the same purpose.    (05)

Unfortunately this is not true... there's a nasty practice called  
"overloading" where a single column/field/data element/attribute will  
contain data that means something different than what is expected.    (06)

A relatively new field of endeavor around databases is called "data  
profiling" (only 121,000 hits on Google... VERY new)... which means  
actually looking into ALL the data in important fields in a database  
to see what's there.    (07)

If I were in command of the ideal world I would ensure that the names/ 
labels of data thingys would actually indicate what is IN the data  
field.  Like having a jug labeled milk that actually contains milk.   
A useful habit that hasn't quite become best practice in the database  
world yet.    (08)
