What is the definition of metadata in the context of data management?

In the context of data management, metadata is defined as "data about data." This includes information that provides context, characteristics, and details about the actual data. For example, metadata can include the source of the data, the date and time it was created, the file format, its size, and any relevant keywords or descriptions that help users identify and manage the data more effectively.

Understanding metadata is crucial because it enables better organization, discovery, and use of data within systems and databases. It essentially acts as a guide that helps users to understand the attributes and relevance of the data they are working with. This allows for improved data governance, enhanced searchability, and supports efficient data management practices.
