'Dana' can also refer to 'Danu', Irish goddess. Czechs use it as a feminine form of the biblical name 'Dan' or a short form for 'Daniela' and 'Bohdana'. This name is used mainly by Arabs of the Persian Gulf, due to their traditional pearl diving professions wherein they gave different type of pearls names. It is used in the Arab world as a female name. In Persian 'Dana' is a name for both girls and boys. It means 'Knowledge' or 'Wisdom'.
