Simple out of order scoreboard example

I am trying to understand the implementation of an out-of-order scoreboard. I referred to Scoreboards | Verification Academy

But it seems too detailed, a bit confusing for a beginner like me, especially the naming convention. Could someone please point me to a simple working example for me to start with?

Thanks.

In reply to UVM_beginner:

An out-of-order scoreboard is an advanced topic that would be hard to describe any simpler than what he cookbook example shows. As a UVM beginner, there’s no need to understand everything about the UVM until you need to.
