    data management?
    A The actual content of a video file. Correct Answer Incorrect Answer
    B The schema of a relational database table. Correct Answer Incorrect Answer
    C The raw data logs of website traffic. Correct Answer Incorrect Answer
    D The rows and columns in a spreadsheet. Correct Answer Incorrect Answer
    E The raw text in an unstructured data file. Correct Answer Incorrect Answer

    Solution

    Explanation: Metadata is "data about data," providing information about the structure, format, and other attributes of data. A database schema is a prime example, as it describes tables, columns, data types, and relationships, enabling users to understand and efficiently use the database. Metadata enhances data discoverability, improves searchability, and ensures proper data management. It plays a vital role in large-scale data ecosystems, where understanding the context of data is essential for effective utilization and compliance. Option A: The content of a video file is the actual data, not metadata. Option C: Raw data logs are primary data sources, not metadata. Option D: Rows and columns represent data, while metadata describes the structure of the dataset. Option E: Raw text files lack the descriptive layer that qualifies as metadata.
