Overview
ISO/IEC TR 20547-2:2018 - Information technology - Big data reference architecture - Part 2: Use cases and derived requirements documents a broad set of real-world big data use cases and the technical requirements derived from them. The report gathers contributed examples from industry, academia and government to identify common big data technical considerations, priorities, and barriers to adoption. It is part of the ISO/IEC 20547 series that defines a reference architecture for big data systems.
Key topics and technical requirements
This technical report focuses on practical, use-case-driven insight rather than prescriptive technology stacks. Major topics covered include:
- Use case properties and templates - standardized survey fields for describing the problem, current solutions, data characteristics and analytics needs.
- Big data characteristics - volume, velocity, variety and other domain-specific data traits that influence architecture and operations.
- Big data science - analytic workflows, experimental and production models, and requirements for reproducibility and performance.
- Use case–derived technical considerations - prioritized requirements and challenges that affect deployment, such as scalability, interoperability, data management, security, preservation and analytic performance.
- Requirements analysis and features - consolidated summaries that translate use cases into actionable architecture needs.
- Extensive domain coverage - dozens of use cases across government, commercial, defense, healthcare, life sciences, deep learning/social media, research ecosystems, astronomy, earth/environmental science and energy.
Annexes provide submitted case studies, a summary of key properties and detailed technical considerations for each use case.
Practical applications and users
ISO/IEC TR 20547-2:2018 is useful for:
- Enterprise and solution architects designing big data reference architectures and choosing components.
- Data engineers and platform teams evaluating requirements for storage, processing, ingestion and analytics.
- Researchers and academic groups comparing cross-domain big data needs and reproducibility practices.
- Government agencies and policy makers assessing legal, preservation and operational implications of large-scale data projects.
- Vendors and integrators developing products or services aligned to common big data challenges.
Practical uses include requirement elicitation for new big data projects, gap analysis of existing platforms, and informing procurement and compliance decisions.
