MongoDB Atlas and Dataworkz's retrieval-augmented generation (RAG) as a service solution enables retailers to combine operational data with relevant unstructured information, creating transformational experiences for customers. This approach leverages generative AI and advanced search capabilities to deliver precise insights on demand, driving operational efficiency and enhancing customer experiences. By integrating RAG with MongoDB Atlas's cloud-based, distributed setup, retailers can build agentic workflows that combine lexical and semantic search with knowledge graphs to fetch the most relevant data from unstructured sources before generating AI responses. This combination gives ecommerce brands the power to personalize experiences at a vastly larger scale, improving engagement, optimizing inventory, and providing scalable, adaptable AI capabilities.
