What is Metadata?
Metadata is structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use, manage or govern an information resource. That includes the characteristics of any data object, such as its name, type, location, author, date created, and size, together with relationships with other data objects.
What is Metadata Management?
Metadata Management can be defined as the end-to-end process and governance framework for creating, controlling, enhancing, attributing, defining and managing a metadata model. It is like a GPS for a data landscape that helps you know what your data is, where does it come from and where does it go.
It can be used for business reasons, for example to make information self-explainable to business users or to ensure compliance through information traceability for regulations, such as GDPR.
It can be also used for technical reasons, for example to anticipate the impact of a change, automatically generate data structures across tools and applications, or facilitate the movement and migration of data between systems.
