Sascha and I at zettelkasten.de may sound like we insist a bit too much
on the unique ID. If you model your knowledge database in a relational
SQL database, that's a perfectly fine implementation as you just
described: the fact that you can work with it is the ultimate test. SQL row ID 
references are a natural match.

But with databases it is like it is with backups: you should be testing
the worst case some day. It might be advisable to look into ways to
export the SQL database into another format and retain the
cross-connections. It's all baked into the text of a paper note or a
plain text note, so this is unique to digital database systems. (Betting
on SQL to not go away isn't a very risky bet, though :))
