Metadata is data about data, providing descriptive information about the characteristics or context of a primary data object. In the case of a PDF file, metadata includes attributes such as file size, author, creation and modification dates, and file format. These details help in managing, organizing, and retrieving the file efficiently. Metadata is critical in data management systems for indexing and searching files, ensuring effective data governance and usability. For instance, knowing the author and creation date of a file enables users to verify its credibility and relevance for specific tasks. Why Other Options Are Incorrect: • A: The actual content of a PDF is primary data, not metadata. • C: A summary is processed or secondary data, not metadata. • D: Employee performance metrics in a database are primary data, whereas metadata would describe the table structure, columns, or relationships. • E: A text message is raw data; metadata would describe its sender, recipient, timestamp, etc.
