Sale definitions

There are two types of sales available:

• Simple: "Buy N * productX for Y"
• Bundle: "Buy N1 * productX1 + N2 * productX2 + ... for Y"

Attached pdf with the database model used: checkout-data-model.pdf

The model enables flexible defining of Sales of the aforementioned types.

When defining the sales definitions you need to pay attention to the restrictions / rules:

• There can be only one PromotionDefinition component for the "Simple" sale type promotionDefinition.overallPriceForQuantity! = null
• There can be many PromotionDefinitions for everyone for the "Bundle" sale type promotionDefinition.overallPriceForQuantity == null. The price is defined in related to Promotion Bundle.price The priority for billing is Simple type promotions, in order of the largest volumes (quantities), followed by Bundle.
