Jonker, A, & Gomstyn, A. (2025). Structured vs. Unstructured Data: What's the Difference? IBM Data Management Guide. https://www.ibm.com/think/topics/structured-vs-unstructured-data

This educational guide from IBM clarifies the fundamental distinctions between structured, unstructured, and semi-structured data while exploring their roles in modern business and technology. The text defines structured data as highly organized information that fits into rigid schemas like spreadsheets, whereas unstructured data represents the vast majority of enterprise information, including diverse formats like video, email, and social media. By comparing these categories, the authors highlight how artificial intelligence and machine learning are increasingly used to extract value from complex, non-formatted datasets. Ultimately, the resource serves as a comprehensive framework for understanding data management, helping readers navigate the trade-offs between the easy accessibility of organized tables and the flexible, high-volume potential of raw data.
