The administration of data that describes other data is known as metadata management. Metadata management aims to make it easy for someone or a program to find a specific data asset. This necessitates the creation of a metadata repository, its populating, and making the information in the storage accessible. Metadata encompasses a lot more than just data descriptions. Every day, metadata takes on new functions as data complexity grows. Metadata may be about the business viewpoint of quarterly sales in some circumstances. It may refer to the data warehouse's source-to-target mappings in other circumstances. It's all about context after that.
