Выражение встречается в следующем контексте:
There are only 46 different annual levels, associated with the years 1959-2004 (the 2005 level is not available at this time). Therefore, it makes sense to store this information in a JavaScript object. Even if we choose to display the monthly levels associated with those years with this tool (over 500 separate numbers), it still might make sense to store the data on the client. No database or extra server hits are required.
