Data 360 is optimal for Agentforce—agents get real-time access to unified customer data with built-in governance (Einstein Trust Layer). But you can connect external warehouses via APIs if you have them. Choice depends on your data stack (do you have a modern warehouse? Is it already unified?) and agent complexity (simple agents with warehoused data are fine; complex agents with unstructured data need Data 360’s architecture). We evaluate your stack and recommend the best fit.
