[Koha] KOHA for Archives

[rafael.antonio at sapo.pt]

Hello

I am working with Koha in Portugal and very soon I will send staff  
translation which is being finished.
I would like to ask and sugest an improvement for Koha allowing to  
work simultaneous with several databases (Koha1, Koha2, etc.) Instead  
to have just one MySQL database. How can we select an alternative  
database with the same framework?
If we can do it I will develop a MARC framework for Archives and then  
we could cope both with libraries and archives. The only thing is to  
change framework and switch between databases.

Best regards,

Rafael Antonio
