If you need different applications to routinely access each other's
tables, why not assign them to different schemas in one database?
I just saw another use case here.
There are lots of offices / departments creating maps. Topography maps,
pipeline maps, nature conservancy (e.g. where are the nests from endangered
birds?), mineral resources, wire maps, street maps, bicycle / jogging maps,
tourists maps, tree maps, cadastral land register, and so on.
All this departments have their own databases for their own maps.
They only map their own stuff.
Towns / states / regions have a department where all these maps get
collected.
You can go to your town and ask for weird maps today - e.g. a map with
all jogging
routes and waste water pipes but without autobahns.
You could say that you have one database per layer.
As I said - I saw this construction in real world outside. I am pretty
sure that other
states maybe have other solutions but the described solution exist.
