My solution with the views is using a time dimension table to place the weekly amounts within the appropriate month-to-date and year-to-date columns.

Does your solution use Oracle's Time Series support?

Does your solution generate multiple rows for each row in the table?

Does your solution use views?

Does your solution store the values in an aggregate table?
