Architectural Interview
Every day for the last thirty years each weather station in the U.S. sends the National Weather Service their 10-day forecast and the previous day’s weather.
The data looks something like this:


name, date, type, lat, long, high, low
potrero hill station, 2014-06-16, actual, 37.7572N, 122.3999W, 62, 55
potrero hill station, 2014-06-17, predicted, 37.7572N, 122.3999W, 67, 53


potrero hill station, 2014-06-18, predicted, 37.7572N, 122.3999W, 74, 58


The National Weather Service decides it wants to make this data easily accessible in a form that clients, both large and small, can use. These clients could be weather specific websites, other websites, newspapers, etc.
How would you go about letting other parties get this information?
