In information science and information technology, single source of truth (SSOT) architecture, or single point of truth (SPOT) architecture, for information systems is the practice of structuring information models and associated data schemas such that every data element is mastered (or edited) in only one place, providing data normalization to ...
Single-source publishing is most often understood as the creation of one source document in an authoring tool and converting that document into different file formats or human languages (or both) multiple times with minimal effort.

The essay was published in book form in May 1849 and is structured with eight chapters; an introduction and one chapter for each of the seven 'Lamps', [2] which represent the demands that good architecture must meet, expressed as directions in which the association of ideas may take the observer: [3]
Architectural decisions influence and impact the non-functional characteristics of a system. Each architectural decision describes a concrete, architecturally significant design issue (a.k.a. design problem, decision required) for which several potential solutions (a.k.a. options, alternatives) exist.
The Enterprise Architecture Body of Knowledge (EABOK) is a guide to Enterprise Architecture produced by MITRE's Center for Innovative Computing and Informatics, and is substantially funded by US government agencies. It provides a critical review of enterprise architecture issues in the context of the needs of an organization.
