Metadata is often described as "data about data," but this definition only scratches the surface. Metadata provides essential background and context, enabling both business and IT users to create and use data and IT systems with complete confidence. It serves as the golden thread that stitches together enterprise-wide landscapes, even those that are heavily distributed and heterogeneous. By offering insights into data origins, structures, and relationships, metadata enhances data quality, consistency, and usability, thereby playing a pivotal role in effective data governance and analytics.
