WO application I am working on was pretty simple up to
this point: one apache webserver and one database
server serving data to it. The things turned more
complicated now: In addition to the first database, we
now want to add access to another database. Both of
these databases have identical schema, and the tables
in question are identical. Think of the second
database as a backup.


The discussion been interesting and all but why not just set up some sort of replication scheme at the database level? I think all the RDBMs popular on this list can do that....



The original author, Milan, isn't replicating the object, he's migrating it in that he's copying the record from database1 to database2, then deleting the copy in database1.


I suspect some kind of audit trail, like he doesn't really want to "delete" the object, as much as mark it deleted by moving it into the other database. So if I'm following the code correctly, the second database ends up being a record of all the objects that have been deleted.

Which, as I said, there's much easier ways to do...so I was hoping Milan would talk about the real problem...
