Semantic layer vs context layer: where BI modeling ends & AI grounding begins

In the evolving landscape of business intelligence (BI) and artificial intelligence (AI), the semantic layer and context layer serve distinct yet complementary roles. The semantic layer is essential for standardizing business metrics, ensuring that data is consistently defined and accessed across BI tools, primarily through SQL-based processes. However, its limitations become apparent when used for AI applications, which require dynamic, real-time data access, memory, and the ability to handle both structured and unstructured data. This is where the context layer comes in, providing a runtime environment that manages an AI agent's access to necessary information, including real-time retrieval, memory persistence, and permission filtering. This layer supports probabilistic reasoning and multi-step inference, enabling AI agents to function effectively with up-to-date and contextually relevant data. Together, these layers ensure that AI systems are not only grounded in accurate business logic but also equipped to handle complex, real-time decision-making processes. Redis offers an integrated solution for this context infrastructure, facilitating efficient data retrieval and memory management for AI workloads.
