About Cloudera Data Catalog

Cloudera Data Catalog helps you understand data lying in your data lake. You can locate relevant data of interest based on various parameters. Using Cloudera Data Catalog, you can understand how data is interpreted for use, how it is created and modified, and how data access is secured and protected.

Cloudera Data Catalog is a service within Cloudera that enables you to understand, manage, secure, and govern data assets across the enterprise.

Cloudera Data Catalog enables data stewards across the enterprise to work with data assets in the following ways:
