FAQ
How detailed should ERDs be for discovery?
Keep them lightweight: entities, keys, and main relationships. Add columns only where semantics matter.
Can AI enforce naming standards?
Yes. Include examples of approved names so AI proposes consistent patterns.
How do I avoid over-clutter?
Split by domain or use multiple views (core vs extended). Link them together with glossary terms.
