本文件规定了大数据参考体系结构（BDRA）。参考体系结构包括概念和体系结构视图。 本文件中规定的参考体系结构定义了两种体系结构观点: -定义大数据生态系统中的角色/子角色、它们之间的关系和活动类型的用户视图； -功能视图定义了架构层和这些层中的功能组件类，这些层实现了用户视图中角色/子角色的活动。 BDRA旨在: -为各利益相关者提供共同语言； -鼓励遵守共同标准、规范和模式； -提供解决类似问题集的技术实施的一致性； -促进对大数据中复杂操作的理解； -在整体大数据概念模型的背景下，说明并理解各种大数据组件、流程和系统； -为政府部门、机构和其他消费者理解、讨论、分类和比较大数据解决方案提供技术参考；和 -促进对互操作性、可移植性、可重用性和可扩展性候选标准的分析。

This document specifies the big data reference architecture (BDRA). The reference architecture includes concepts and architectural views. The reference architecture specified in this document defines two architectural viewpoints: — a user view defining roles/sub-roles, their relationships, and types of activities within a big data ecosystem; — a functional view defining the architectural layers and the classes of functional components within those layers that implement the activities of the roles/sub-roles within the user view. The BDRA is intended to: — provide a common language for the various stakeholders; — encourage adherence to common standards, specifications, and patterns; — provide consistency of implementation of technology to solve similar problem sets; — facilitate the understanding of the operational intricacies in big data; — illustrate and understand the various big data components, processes, and systems, in the context of an overall big data conceptual model; — provide a technical reference for government departments, agencies and other consumers to understand, discuss, categorize and compare big data solutions; and — facilitate the analysis of candidate standards for interoperability, portability, reusability, and extendibility.
