观热点：Single source of truth concept(单一资源真相概念，个人翻译)

不管是啃文档还是软件开发，我们都没有离开软件工程的一些概念的问题，如果不整合这些比较底层的基础，遗忘曲线这种东西是扛不住的，虽然文档也是开箱即用，还是做点记录也当个人系统知识的补缺，顺便练英语。

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 a canonical form (for example, in database normalization or content transclusion).

在信息科学和信息技术中，信息系统的单一真实源（SSOT）架构或单一真实点（SPOT）架构是结构化信息模型和相关数据模式的实践，使得每个数据元素仅在一个地方被掌握（或编辑），提供数据规范化为规范形式（例如在数据库规范化或内容转化）。

VUEX 基于设计的框架理念是基于SSOT的，作为单一真实源的架构体系来分隔各个组件状态之间的联系。

Any possible linkages to this data element (possibly in other areas of the relational schema or even in distant federated databases) are by reference only. Because all other locations of the data just refer back to the primary "source of truth" location, updates to the data element in the primary location propagate to the entire system, providing multiple advantages simultaneously: greater efficiency/productivity, easy prevention of mistaken inconsistencies (such as a duplicate value/copy somewhere being forgotten), and greatly simplified version control. 

与此数据元素的任何可能链接（可能在关系模式的其他领域，甚至在遥远的联合式数据库中）仅通过参考。因为数据的所有其他位置只需回到主要的“真相来源”位置，因此对主要位置中的数据元素的更新会传播到整个系统，同时提供多个优势：更高的效率/生产力，轻松预防错误的不一致之处（例如在被遗忘的地方进行重复的值/复制），并极大地简化了版本控制。

Without SSOT architecture, rampant forking impairs clarity and productivity, imposing laborious maintenance needs.

如果没有SSOT体系结构，那么猖獗的分叉会削弱清晰度和生产力，从而带来费力的维护需求。

Deployment of an SSOT architecture is becoming increasingly important in enterprise settings where incorrectly linked duplicate or de-normalized data elements (a direct consequence of intentional or unintentional denormalization of any explicit data model) pose a risk for retrieval of outdated, and therefore incorrect, information. Common examples (i.e., example classes of implementation) are as follows:

SSOT体系结构的部署在企业环境中变得越来越重要，在这些环境中，错误链接的重复数据元素或非标准化数据元素（任何显式数据模型的有意或无意非标准化的直接后果）会带来检索过时信息的风险，从而导致错误信息。常见示例（即实现的示例类）如下：

In electronic health records (EHRs), it is imperative to accurately validate patient identity against a single referential repository, which serves as the SSOT. Duplicate representations of data within the enterprise would be implemented by the use of pointers rather than duplicate database tables, rows, or cells. This ensures that data updates to elements in the authoritative location are comprehensively distributed to all federated database constituencies in the larger overall enterprise architecture. EHRs are an excellent class for exemplifying how SSOT architecture is both poignantly necessary and challenging to achieve: it is challenging because inter-organization health information exchange is inherently a cybersecurity competence hurdle, and nonetheless it is necessary, to prevent medical errors, to prevent the wasted costs of inefficiency (such as duplicated work or rework), and to make the primary care and medical home concepts feasible (to achieve competent care transitions).

在电子健康记录（EHR）中，必须根据单个参考存储库（即SSOT）准确地验证患者身份。

企业内数据的重复表示将通过使用指针而不是重复的数据库表、行或单元格来实现。

这确保了对权威位置中元素的数据更新被全面分发到更大的整体企业体系结构中的所有联邦数据库选区。EHR是一门很好的课程，可以说明SSOT架构是如何实现的，这是非常必要的，也是一个挑战：这是一个挑战，因为组织间健康信息交换本质上是一个网络安全能力障碍，尽管如此，还是有必要防止医疗错误，防止低效的浪费成本（如重复工作或返工），并使初级护理和医疗院概念可行（以实现称职的护理过渡）。。

Single-source publishing as a general principle or ideal in content management relies on having SSOTs, via transclusion or (otherwise, at least) substitution. Substitution happens via libraries of objects that can be propagated as static copies which are later refreshed when necessary (that is, when refreshing of the copy-paste or import is triggered by a larger updating event, such as a new scientific advance or a piece of breaking news). Component content management systems are a class of content management systems that aim to provide competence on this level.

Ideally, SSOT systems provide data that are authentic (and authenticatable), relevant, and referable.

作为内容管理中的一般原则或理想状态的单一资源的发布是依赖于具有SSOT的情况，通过交叉或（至少）替代。替换是通过对象库进行的，这些对象库可以作为静态副本传播，然后在必要时进行刷新（即，当更大的更新事件（如新的科学进展或突发新闻）触发复制粘贴或导入的刷新时）。组件内容管理系统是一类内容管理系统，旨在提供这一级别的能力。

理想情况下，SSOT系统提供的数据是真实的（和可认证的）、相关的和可参考的。
