Question

I’m trying to wrap my head around this topic but can’t find a simple solution.

• product based on region price.
• regions have one currency per region and stock per region.
• then there are product variations like color and size, color should be special cause I need images for it.
• color and size is depending on stock based on the region.
• product has one price per region

Maybe anyone here has a good idea for this db layout.

edit

products

• id
• name
• identifier
• slug

product_variations

• id
• product_id
• name
• size
• image

product_stocks

• id
• count
• product_variation_id
• region_id

product_prices

• id
• product_id
• region_id
• price

regions

• id
• name
• slug

still the size is tied to the variations..
i need one variation with multiple sizes and stock should also be linkable to size based on region

Answer 1

May be something like:

Products:

• Id.
• Name.

product variations like color and size, colour.

ProductVariations:

• Id.
• ProductId.
• StockId(color and size is depending on stock based on the region)
• Colour.
• Size

regions have one currency per region and stock per region.

Currencies:

• Id.
• Name.

Stocks:

• Id.
• Name.
• RegionId.

Regions:

• Id.
• Name.
• CurrencyId.
• StockId.

product has one price per region

product based on region price

ProductPrices:

• Id.
• ProductId -> Products table.
• RegionId -> Regions table.
• Price.

You might need to tweak this structure a little bit to accommodate:

• The product images depending on whether you need only one image per product or a product can have many images (new table ProductImages).
• You didn’t clarify the product properties you need(product variations) are they a lot of variations for each product (one to many for each product) or its just a properties for each product.

Update:

one size can have stock as well.

In this case you can move Colour and Size or the size only as you want to a new table, something like, ProductVariationOptions:

ProductVariationOptions:

• Id.
• Size.
• Colour.

Then the your ProductVariationOptions would be like this:

ProductVariations:

• Id.
• ProductId.
• StockId(color and size is depending on stock based on the region)
• ProductVariationOptionsId -> ProductVariationOptions
