In data terminology, what do we call information that is useful for analysis but lacks structure?

Unstructured data is characterized by its lack of a predefined format or structure, making it challenging to analyze using traditional data processing techniques. This type of data includes information that may be qualitative or textual, such as emails, social media posts, images, or video files. Because unstructured data does not adhere to a specific model or format, it often requires advanced analytical tools or techniques, such as natural language processing, to extract meaningful insights.

Other terms mentioned in the choices have distinct meanings: internal data refers to information generated within an organization which might be structured or unstructured; structured data is organized in a defined manner, typically in rows and columns within databases; and data model refers to the conceptual representation of data and its relationships within a system. Hence, the choice of unstructured data accurately captures the essence of information that is useful for analysis but lacks a defined structural format.
