The term metadata in data management refers to data that provides information about other data. This can include details such as the origin, format, structure, and context of the primary data. Metadata plays a crucial role in organizing, discovering, and managing data effectively, making it easier for users to navigate and utilize datasets. For instance, in a library, the metadata for a book might include the title, author, publication date, and genre, enabling efficient search and retrieval. Overall, effective management of metadata enhances data accessibility and fosters better decision-making processes.
