This page provides an overview of the data models underpinning the National Addressing System, including logical, relational, and distribution models. These models define how addressing data is structured, stored, and shared across systems.

• The logical model outlines the core entities and their relationships in a technology-neutral format.
• The relational model translates this into a database schema optimized for storage, indexing, and querying.
• The distribution model specifies how data is synchronized and disseminated to consumers and external systems, supporting both centralized and decentralized implementations through standardized interfaces and APIs.
