?! On the barcode example you gave, "1152019" would mean id=11, size=5, expiry_date=2019; string processing would be needed to extract the size element from stored barcode values for a query, and this would preclude index optimisation of that query clause. And naturally, vendor-specific barcodes will have errors, and their mappings will change over time. It'll devolve into an unusable mess.
