[Opensim-users] Database overview needed

[Impalah]

Not, there aren't any, at least in the "original" opensim servers.

Asset server is a huge store of anything, even the generated maps and
terrain revisions (opensim region servers). Not only inventory assets are
stored there.

Asset server and inventory server are separated processes each one with
their own data models. The connection between them is
assetID(inventoryItems)->id(assets) but there aren't any foreign keys. You
could use different databases for assets/inventory.

I have only doubts about the new AssetsInventory server, I hadn't time to
play with it.
