What type of data is considered 'unstructured'?

Unstructured data refers to information that does not have a pre-defined data model or structure. This type of data is typically more complex and can come in various forms, such as text, images, videos, or social media posts. The lack of a uniform format makes it challenging to categorize and analyze using traditional data processing techniques.

When we think about unstructured data, it's clear that it cannot easily fit into a spreadsheet or database with specified fields or rows. For example, a collection of customer reviews on different platforms would be considered unstructured because it varies in text length, format, and sentiment without a consistent framework guiding its analysis.

On the other hand, the other choices reflect structured data characteristics. Data organized in a predefined manner or that has a clear data model follows specific formats, making it easier to analyze and manage. Similarly, data that primarily consists of numbers is often structured, typically allowing for straightforward mathematical operations and statistical analysis.
