Canonical Schema

A canonical schema creates a shared representation of data that multiple systems can understand. Instead of building separate data mappings for every system-to-system connection, applications translate their data into a common canonical format. The schema typically defines fields, data types, relationships, and naming conventions to ensure information is represented consistently across connected environments.

Organizations often operate multiple systems that store and structure data differently. A canonical schema reduces integration complexity by providing a consistent data format between them. This can improve interoperability, simplify data exchange, reduce duplicate transformations, and make integrations easier to maintain as systems evolve.
