-- This is the core database schema for ScanCore.

-- NOTE: network_interfaces, network_bonds and network_bridges are all used by scan-network (which doesn't 
--       exist yet).

-- This stores information about network interfaces on hosts. It is mainly used to match a MAC address to a
-- host. Given that it is possible that network devices can move, the linkage to the host_uuid can change.
