Unfortunately, for developers, TBDITW don't allow change column names,
datatypes, nullability, etc...
At least, no without large efforts (like creating a new table, migrating
all data to new table, dropping constraints & table, creating a table
with correct columns, copying data back, recreating constraints...)
So is still necessary to develop in another database of preference (to
get speed and productivity), then migrate to Derby... and cross fingers
to not need change anything after app is in production, because changing
a column on a table with million of records take hours... and need too
much attention to not make mistakes, then I give it up. Forget. I can't
deal with Derby in production, not now... I'll be very happy when this
would be possible.
Anyway, it's a great database... work like a charm in static database
schemas...
Sorry by the rant,
Richter

This is great news, both for our team and for developers. Developers
get the Best Database In the World (TM) out-of-the box, and Derby will
likely get a lot more users and attention!
