Full title and description

ISO/IEC TR 20547-2:2018 — Information technology — Big data reference architecture — Part 2: Use cases and derived requirements. This technical report collects representative big data use cases across application domains and derives technical considerations and requirements that inform the Big Data Reference Architecture (BDRA).

Abstract

ISO/IEC TR 20547-2:2018 provides examples of big data use cases, describes their application domains, and extracts derived technical requirements and considerations to guide architects, implementers and decision makers when planning and deploying big data systems. It is intended to inform subsequent parts of the BDRA series by supplying practical, domain-driven requirements.

Scope

This technical report documents a set of contributed big data use cases and, for each, identifies the application domain, principal functional concerns, quality attributes and derived technical requirements. The scope is to provide real-world scenarios and requirements input that can be used to validate and shape the Big Data Reference Architecture and inform interoperability, deployment and standards decisions. The report does not itself prescribe a single architecture implementation but informs architecture design and standards selection.

Key topics and requirements

• Collection of representative big data use cases across domains (e.g., healthcare, finance, manufacturing, smart cities, IoT and research).
• Derived functional requirements for data ingestion, storage, processing and analytics.
• Non‑functional requirements: scalability, performance, availability, latency, and reliability.
• Interoperability and portability considerations between big data components and systems.
• Data governance, metadata management, provenance and cataloguing requirements.
• Security and privacy considerations as they relate to use-case requirements (relationship to Part 4 on security and privacy).
• Operational and lifecycle concerns: monitoring, maintenance, and evolution of big data solutions.
• Guidance to map use-case requirements to architectural components and standards choices.

Typical use and users

Used by enterprise architects, solution architects, data engineers, platform teams, standards bodies, procurement and policy teams to understand real-world big data requirements and to derive or validate architectural decisions. It is also useful to researchers and vendors who want examples of domain-specific requirements to inform product design and interoperability efforts.
