Porozumeni zadani

Zdravim, v ramci pohovoru delam podle zadani v anglictine jeden projekt. Ovsem si nejsem uplne jiste u jedne pasaze.. "Adds a HN story to a collection and persists a snapshot of the conversation fetched from thehttps://github.com/HackerNews/APIin the database.You don't have to sync all the fields, justthe most important ones (eg. time, content, author). " Konkretne: "persists a snapshot of the conversation". Databaze se ma pouzivat SQLkova, mam tabulku komentare, story a tabulku ktera je spojuje (story has comment). Tedy v momente pridani kdyz tohle vsechno pridam do db a ulozim. Tak mam hotovo a nic vic se tim nemysli? 

Snapshot je jednoduse zaznam dat v danem okamziku, nic vic. Tj. pokud stahnes ta data z githubu v 11:03, mas snapshot dat z 11:03. Pokud nekdo prida komentar v 11:04, v tom tvem snapshotu uz nebude... Takze ano, uloz to a mas hotovo :)
