"When creating a new linked universe or adding a core universe, you have a choice to reuse the core universe connection or use another compatible connection that allows you to access components outside of the core universe. It is recommended that you use another connection."
Does this mean that my core universe and linked universe can be pointing to two different relational database connections? For example the core universe is pointing to a sales database from region A while the linked universe is pointing to a sales database from region B? The underlying database schemas would be the same in this example, the only difference would be that each region's sales data would be in the specific database.
