What is a key characteristic of unstructured data?

Unstructured data is characterized by its lack of a predefined data model, which means it does not conform to a specific structure or format that can be easily stored in traditional databases. Instead, it encompasses a wide variety of formats, including text documents, images, audio files, and videos. This diversity in format makes unstructured data robust and rich for analysis, as it can contain valuable insights that structured data might not capture.

The presence of text, images, and videos highlights the complexity and richness of unstructured data, as these elements generally do not fit neatly into conventional table-like structures typically used with structured data. Consequently, unstructured data is pivotal in various fields where context and qualitative information are crucial.
