I can't add the tables to the first database as I want to use that 'as
is' and hence read only.

As a beer drinker, I am a member of CAMRA - http://www.camra.org.uk/
They have an app for iOS and Android and while I do have the Android
app on my phone I think it's awful. So I'm trying to write an app to
use the CAMRA database which happens to be a sqlite file. CAMRA update
the app and data annually and I want to be able to simply overwrite the
existing database with the new one each year but retain my own database
for noting things like which beers I've drunk.
I've checked with the company that wrote the app for CAMRA and they say
that they try to maintain the same database structure and numbering
each year but it falls to CAMRA to maintain the numbering as they
supply the data to the app company. I'm assuming (perhaps naively) that
it will remain constant.
I might also have another app for noting which pubs I've visited as
CAMRA list pub data in the same sqlite database.

Thanks very much. That gives me something to work with.
I apologise if my first reply was a bit terse. That wasn't my intention.
