Probably using the same relationship that objects have inside the vCenter Database. Here is the current diagram form the Vmware documentation. At the root of the tree, there is a folder; it contains the datacenter object. Underneath the Datacenter object is several other folders containing related objects. One for hosts, one for VMs, one for Networks and one for Storage. Click HERE to read more.
