You will often hear or see the term RDBMS or Relational Database Management System. This term refers to a subset of DBMS, not an alternative, and is specific to those DBMS that handle relational database formats. The term SQL is often incorrectly applied to these, but SQL is a language and relational databases are a mathematical model. While the two have a relationship (no pun intended) they are different things completely and are not directly tied together. Today, what is and is not an RDBMS is increasingly unclear as nearly all DBMS have some relational element and even the most traditional RDBMS stalwarts have begun to add non-relational engines or options.

What would you call Xbox One system, a hypervisor or OS?
http://wccftech.com/xbox-one-architecture-explained-runs-windows-8-virtually-indistinguishable/

If the article is accurate it would have to be a hypervisor. With a dom0 running an anorexic windows 8.

Sounds like they use the term RTOS as a code for hypervisor. They say it is an RTOS but then point out that it is not an OS (in that it doesn't run apps) and that it is a hypervisor (in that it hosts Windows 8.) So either their name is wrong, or their description is.

Ok, I didnt read the article, I commented based on things i heard from Paul Thurrott.

So I'll admit my understanding might have been wrong.

As a side note, Xbox one has been upgraded to Windows 10 now....

It's weird that the article claims it's a partition not a VM....

Partition and VM are not competing concepts. Lots of VMs are partitions. One thing (VM vs physical) is about how it runs. Partition vs. something else is just where it is stored. Nothing in saying it is a partition suggests that it is not a VM.

Now we only have the article to go on, but the article seems pretty clear that it is a VM. But what it really is, no idea.
