Shows concrete MySQL specifics: exact storage sizes for INT family storage bytes, when VARCHAR temporary to MEMORY conversion inflates RAM, blob/text limits (65KB, 16MB), and charset pitfalls like utf8mb4 vs utf8mb3. Gives actionable defaults (unsigned INT primary keys, index both sides of relations), describes using generated columns indexed (MySQL 5.7/8.0) and warns about unnecessary engines or tuning. Useful if you want precise rules and gotchas, not high-level theory.
