Product#
A Product is stored in a hierarchical structure, in which the Product is broken down into Variants and Sizes. The Product represents a certain design. Variants are different versions of the same product, typically different colors. Sizes are the different sizes you can buy the style in. This product structure enables very efficient product information management.
Most information is stored on the Product level, where you find the Folder, Collection and all basic information such as Country of Origin, HS Code and Material Composition. All products have at least one Variant and all Variants have at least one Size, even if it is a one-size product.
The Variant level focuses on media (images) and a few attributes, notably color.
Besides actual size, the Size level stores GTINs (UPC or EAN codes). Stock inventory is stored on the Size level, as the size represents the physical item that exists in a warehouse.
