Process for database changes?

[Jeremy Boynes <jb...@apache.org>]

I started to look at applying my fix for DERBY-89 but I have a couple of 
concerns about changes to the data dictionary.

At one level we can keep this simple and store the full signature in the 
dictionary; this will keep the schema the same but will mean that values 
from the latest release may be incompatible with older versions. Given 
that problem exists I am tempted to take this further and actually add 
the parameter mappings to the dictionary to avoid having to reparse the 
signature every time.

Anyway, both of these hit the problem Dan orginally raised about not 
having a process defined for changes to the physical database. I would 
like to open this thread to resolve that.
