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)
