NoSQL databáze jsou reakcí na exponenciálně rostoucí objemy dat generovaných z moderních distribuovaných systémů s mnoha aktéry. Největším tématem zde jsou sociální sítě, kde jsou aktéři fyzické a právnické osoby v této síti komunikující a prezentující se. Podobným příkladem je samotný internet, respektive hardware a software, který internet tvoří. Jako roste počet uživatelů internetu i objem přenesených dat a šířka připojení, roste i počet zařízení, služeb a aplikací produkujících a vyměňuj ...
