N+1 Query Problem
Code fetches a list with one query, then issues one additional query per row (typically ORM lazy loading), so total cost is dominated by N network round trips and per-statement overhead rather than database work. The fix is set-based access: a JOIN, an IN/ANY batch fetch, or the ORM's eager-loading mechanism.
