Metadadatnyilvántartás

Metadadatnyilvántartás, often translated as metadata registry or metadata repository, refers to a system designed to store, manage, and make accessible metadata. Metadata, in essence, is data about data. It describes the characteristics of other data, providing context and information about its origin, format, structure, meaning, and relationships.

The primary purpose of a metadadatnyilvántartás is to facilitate understanding, discovery, and effective use of data assets within an organization or system. It helps users find the data they need, understand its quality and limitations, and ensure its appropriate application. This is crucial for data governance, data integration, data warehousing, and data analytics initiatives.

Key functionalities of a metadadatnyilvántartás typically include cataloging data assets, documenting data definitions and business terms, mapping data lineage (tracking data flow and transformations), managing data quality rules, and controlling access to metadata. It acts as a central authoritative source for information about an organization's data landscape.

By providing a structured and searchable repository of metadata, a metadadatnyilvántartás promotes data transparency, reduces data redundancy, and improves overall data management efficiency. It empowers users to make more informed decisions based on a solid understanding of the underlying data. The implementation and maintenance of such a registry are often key components of a comprehensive data strategy.
