Microsoft Azure Data Fundamentals DP-900 Practice Question

Semi-structured data, such as JSON or XML, does not rely on a rigid table schema. Instead, it carries its own self-describing structure through tags or key-value pairs, allowing records to contain optional or variable attributes. Structured data, by contrast, is organized into relational tables with predefined columns and data types. Unstructured data (for example, video files) lacks an internal organizational model beyond basic metadata, while graph data stores focus on nodes and edges rather than tagged elements. Therefore, the description referring to flexible, self-describing tags is the only accurate characterization of semi-structured data.
