SOT — Source of Truth

The authoritative source of specific information recognized as the official reference for a defined dataset or business domain.

Definition

A Source of Truth (SOT) is the authoritative system, repository or information source designated as the official reference for a particular class of information. A Source of Truth establishes ownership, accountability and governance for data, ensuring that users and connected systems reference consistent and validated information.

Why It Matters

A Source of Truth provides the authoritative reference for a defined set of information within an organization.

In Practice

A Source of Truth may exist for individual business domains, whereas a Single Source of Truth represents the broader information management principle of maintaining one authoritative source for each class of information.

Common Misuse

A Source of Truth identifies the authoritative repository for a specific dataset, whereas Single Source of Truth describes the broader organizational principle of managing authoritative information consistently across multiple business domains.
