A Parent-Child data model is a structured way of representing products with variations.

For example, a shirt available in sizes S, M, and L, and in colors Blue or Black.

• The Parent is the base product.
• The Children are the specific variants.
• All children share the same Parent SKU.
• Each variant has its own attributes, such as Size = M or Color = Blue.

Most marketplaces require this structure so that all variations appear together under a single product listing.
