Data models are the collected structural specifications that define how information is represented, related and constrained within a system or framework. In digital-twin and layered service architectures they describe the shape of state, telemetry and interactions exchanged between components. Well-defined data models are a prerequisite for interoperability, validation and consistent behaviour across service layers.

- In a digital twin, data models define the synchronised representation of a physical asset’s state and telemetry. Across layered architectures they provide the shared contracts that let services exchange and validate information consistently.
