Question
Which of the following is the most accurate description
of semi-structured data ?Solution
Explanation: Semi-structured data, such as JSON (JavaScript Object Notation) files, lies between structured and unstructured data. It has an organized schema (e.g., key-value pairs) but does not conform to strict tabular formats like relational databases. JSON is widely used in APIs, web applications, and NoSQL databases because it allows flexibility while still enabling data to be queried or processed programmatically. Unlike structured data, which requires predefined schemas, semi-structured data provides adaptability for evolving datasets. JSON's format, combining hierarchy and flexibility, is a hallmark of semi-structured data. Option A: Relational databases store structured data in tables, which is not semi-structured. Option B: Videos and images without metadata are unstructured data, lacking any predefined schema. Option D: Plain text documents without formatting fall into the unstructured category, not semi-structured. Option E: Categorical data relates to types of variables, not data formats.
