PerProduct

Perproduct is a descriptive term used in software development and e-commerce to refer to processing, pricing, rules, or data transformations that are applied on a per-product basis rather than to the collection as a whole. The concept emphasizes item-level operations, where each product in a catalog is handled independently rather than in bulk.

In practice, perproduct processing is implemented by iterating over product items and applying per-item logic. This can be done through explicit loops, functional map operations, or per-item pipelines in data processing frameworks. Common use cases include applying individual pricing rules or discounts, performing per-product data validation and enrichment, updating stock or attributes on a per-item basis, and generating per-product analytics or reports.

Benefits of perproduct approaches include isolation of concerns, easier debugging for individual items, and natural parallelization opportunities, since each product can often be processed independently. Potential drawbacks include higher computational or memory overhead compared to bulk operations, latency in large catalogs, and the need for robust error handling to avoid cascading failures from a single problematic item.

Terminology notes: perproduct is not a universally standardized feature with a single official specification. It is typically used descriptively in documentation and code to indicate item-level logic. Variants such as perProduct or PerProduct may appear as function names, namespaces, or configuration keys in different systems. When encountered, the exact behavior depends on the surrounding context and implementation.
