Usage Notes

完整 emphasizes that nothing is missing from a whole, while 完全 (wánquán, completely/entirely) is an adverb emphasizing degree. Compare: 资料完整 (the data is complete, nothing is missing) vs. 完全正确 (completely correct). 完整性 (wánzhěng xìng) means "completeness" or "integrity" and is used in data science, law, and archival work.

Memory Hook

完 means "to finish/complete" and 整 means "orderly/whole." Something 完整 is fully finished and in perfect order, with every piece in its rightful place.
