Each style has a description, but the same description may apply to several styles. Weekly-Sales represents the number of shoes of a particular size and style sold in the previous week. Monthly-style-value is the total sales value in the previous month for each style. Draw an FDD for the data elements Style-Number, Description, Size, Weekly-Sales, Monthly-Style-Value.
