View Content of different Tables on one List page

I have different Tables (Printers, Monitors, PC, Software and Users).

Each of this tables has more fields eg. IP-Address, Serial-Number, Resolution. One Field is the same in all Tables, the username from table users.
What I want to see is this:

1. A Listpage with the username, eg. IP-Address (from table PC), Resolution (from Monitors), Printername (from Printers)
   
2. In the next row of Listpage, same username, other IP-Address (from table PC because he has 2 PC), nothing because he has only the above monitor (with a switch), another Printername (from Printers because he has two printers)
   

I prefer the above possibility but if this will not work,

perhaps it is possible as a Mastertable with Users (Username) as Master ?
