Data Catalog: Organizing and Discovering Data Assets
A data catalog is a central repository of information about data assets. It provides a single place to find information about where data is stored, what it means, and how it is used. Data catalogs can help organizations to improve data governance, data discovery, and data reuse.

- The name of the data source
- The location of the data source
- The data format
- The data lineage
- The data quality
- The data usage
Data catalogs can be used to:
- Track the lineage of data from its source to its use
- Identify data quality issues
- Ensure that data is being used in accordance with its intended purpose

There are a number of different data catalog solutions available on the market. Some of the most popular include:

- The desired level of integration with other systems
Data catalogs can be a valuable tool for organizations of all sizes. They can help to improve data governance, data discovery, and data reuse.
