    Solution

    Metadata plays a pivotal role in data management by offering detailed descriptions of data assets, allowing for seamless organization and retrieval. For example, in a library management system, metadata for books (title, author, genre, ISBN) allows users to search for and access specific resources efficiently. Similarly, in large-scale data systems, metadata aids in indexing and categorizing vast datasets, ensuring they are accessible and well-organized. Tools like database schemas, file attributes, and XML tags leverage metadata for improved data governance, making it a cornerstone of any robust data infrastructure. Why Other Options Are Incorrect: • A: Metadata describes data; it does not store raw data itself. • C: Metadata complements visualization tools; it cannot replace them. • D: Metadata supports analysis by organizing data but does not directly analyze trends. • E: Metadata describes primary data; it does not replace or substitute it in analytics.
