[Composable DXP] Real-time inventory and promotion orchestration for e-commerce

A DXP should be capable of real-time orchestration of complex e-commerce logic, such as dynamically showing out-of-stock products with filter options, displaying FOMO labels based on inventory, and triggering promotions when inventory is low or order frequency changes. Current methods relying on batch processing or CMS storage lead to stale data and poor user experiences, especially with high SKU volumes.
