Morphology

subdatabase = database (transparent) = sub + data + base

The word is formed by adding the productive prefix 'sub-' (meaning a subdivision or smaller part) to the common compound 'database', making the meaning predictable to learners.

Etymology

The word subdatabase joins the prefix sub- ('under' or 'below') with database ('a stored set of data'). Think of sub- like in subway or submarine to remember it means something smaller or 'under' the main thing, so a subdatabase is a smaller part of a larger database used for a specific purpose.
