Unstructured Data

Definition

Unstructured data refers to information that does not have a predefined data model or organization, making it difficult to analyze using traditional databases. This type of data is typically text-heavy and can include formats such as emails, social media posts, videos, and images. Due to its lack of structure, unstructured data presents unique challenges and opportunities in areas such as machine learning and big data analysis, where extracting insights from diverse data sources is essential for informed decision-making.
