Consider this: you have LLBLGen projects working and everything is just nice, life is beautiful. Then your DBA, for some reason, change the name of the database. How do you manage this as LLBLGen user?
At runtime you can use Catalog Name Overwriting but What about LLBLGen Desinger? How do you refresh changes from your database if the database name changed? Well, this is briefly mentioned at docs, but for some reason users can’t figure this out, so I will try to explain it a little bit more.
