To me, "sequence #'s" usually implies numeric and consecutive, but you
only mentioned using them for unique identifiers. UUID (Universally
Unique Identifier) can also be useful, if a little heavier than
integral id's. Otherwise, Magma has has integral, consecutive
sequence # generators.
Often, however, "record identifiers" can be eliminated when moving to
an object system, since objects have direct references to other
objects.
