2. Shoes are sold in a variety of styles and sizes. A style is identified by a
style number. 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.
How would your diagram change if you incorporated Week and Month, so
historical data of Weekly-Sales and Monthly-Style-Value could be
maintained?
