Product Variation model

A Product Variation model behaves just as a Product model, as it can have multiple barcodes attached, the only difference is that a Product Variation model represents a sub-product (variation) that belongs to a Product model.

A Product Variation model has the following fields:

Field	Description
id	The internal ID of the product variation, this should be used to refer to it. These IDs are always unique.
name	Name of the product variation

Tip

For an real-world, complex example think of a Product model as a combination of a bag and a jacket, sold together. A Product itself can not be bought since we cannot tell what size of jacket the customers want. For this reason we attach Product Variations, with each variation having two barcodes, one for the bag (which is the same for all variations) and one for the jacket (which differs for each variation).
