A single source of truth (SSOT) might be considered a ‘state’ or concept rather than a ‘thing’. The ‘thing’ is what will help to provide you with a single source of truth. That ‘thing’ is the aggregation of all of the data held by an organization, within a single location, providing a single point of reference for all. Put simply, it’s a single destination for all of your data or information, reflecting a single truth.
