vCenter SQL DB - Query VM allocated resources

OK, so we all know vCenter uses a SQL backend DB.

Is it safe to assume that the SQL DB holds a list of all VM's from all clusters in all datcenters it manages?

If so, I would like to query the SQL DB and get a list of all the VM's and how many CPU's are assigned to each VM and how much RAM is assigned to each VM.

Is this possible?

A quick Select query should do it. I' just haven't had time to open the SQL DB to peer into the schema.

Thanks
