    Calculate moving sum of values, year to date




      I am not really familiar with window calculations. i was wondering if windows calcs can be used to sum up values from a given date to a 365 days before? Can someone direct me to a good resouce where I can learn windows calculations better?


      And what do you call the process of manipulating the data before it gets imported into tableau? if anyone has a resource on that it would be most helpful!
