The difference between structured data and unstructured data lies in how it is organized and managed. Structured data is highly organized, typically stored in relational databases, making it easily searchable and analyzable. Examples include data in tables, with clear schema definitions. Conversely, unstructured data lacks a predefined format and can include text documents, images, videos, and social media posts. This data is more challenging to analyze due to its varied formats and lack of consistency. Understanding the distinction is vital for effective data management and analytics strategies.
