A database designed to store metadata
A platform for sharing data
A method for data analysis

The correct answer is: A database designed to store metadata

A metadata repository is fundamentally a database specifically designed to store metadata, which is data that provides information about other data. This includes details such as the source, structure, format, and meaning of the data, allowing users to understand the context and usage of the raw data stored elsewhere. Metadata repositories serve as a crucial component in data management, enabling data governance and ensuring that users can find, access, and utilize data effectively for analysis and reporting. Using the repository, organizations can maintain an organized inventory of their data assets, improve data quality, and facilitate compliance with regulatory requirements. The correct answer highlights the essential purpose and function of a metadata repository, distinguishing it from mere data storage or analysis methods.
