A data analyst is assigned a project to gauge public sentiment about a new product launch. The data consists of social media posts, customer review articles, and video commentary from influencers. Which data structure BEST describes this collection of data?
Semi-structured
Unstructured
Relational
Structured
The correct answer is Unstructured. Unstructured data is information that does not have a pre-defined data model or is not organized in a pre-defined manner. The data sources mentioned-social media posts, review articles, and videos-are classic examples of unstructured data because their content is free-form and does not fit neatly into rows and columns.
