Questions & Answers about Baza danych składa się z dwóch części.
Why is z dwóch części in the genitive case instead of the instrumental case, which usually follows z?
The preposition z takes the instrumental case when it means 'with' (together with). However, when z means 'out of' or 'from,' it requires the genitive case. The verb składać się z means 'to consist of' or 'to be composed of,' so it triggers the genitive case for the components: dwóch części.
Why is 'database' translated as baza danych? What case is danych?
Danych is the genitive plural of the plural-only noun dane (data). Literally, baza danych means 'a base of data'. Since it uses the genitive to show a relationship, danych doesn't change its form even if the main noun baza declines depending on its role in a sentence.
Why is the number two written as dwóch here?
Because the verb phrase składać się z requires the genitive case, the number 'two' must decline into its genitive form, dwóch. It agrees with the noun it modifies, części, which is also in the genitive plural.
