Zero-copy is a data-access pattern in which composable solutions use data where it already resides instead of creating multiple application-specific copies. It preserves a consistent source of truth while reducing costs and security risks. section 9.3.2

A composable marketing system might copy audience membership while leaving personalization fields in place. This is still a useful design when the trade-off is intentional. section 9.3.2
Use zero-copy as a design principle when connecting marketing capabilities to organizational data:
- Combine customer-centric data from a data lakehouse with channel-centric data from an email platform. section 9.3.2
- Assess the architecture by how much data it copies, rather than treating zero-copy as a binary label. section 9.3.2
