Single version of the truth

In computerized business management, single version of the truth (SVOT), is a technical concept describing the data warehousing ideal of having either a single centralised database, or at least a distributed synchronised database, which stores all of an organisation's data in a consistent and non-redundant form. This contrasts with the related concept of single source of truth (SSOT), which refers to a data storage principle to always source a particular piece of information from one place.
