Data Catalog

Data Catalog is a metadata management tool which exists as part of a data management platform, that indexes and catalogs data assets. It enables you to locate and access metadata about data sources, data format types, and data policies. Regardless of your role in an organization, it allows you to better understand the data landscape and make informed decisions about how to use data.

Types of Data Catalogs

There are two types of Data Catalogs:

• Business Catalogs: Business catalogs contain high-level information about data assets, such as their business purpose and ownership. They are designed for business users who need to understand the data landscape without getting into technical details.
• Technical Catalogs: Technical catalogs contain detailed technical information about data assets, such as their schema, data types, and data quality metrics. They are designed for data engineers and other technical users who need to work with data directly.

How to Use a Data Catalog

The most common way to use a Data Catalog is to search for data assets. You can search by keyword, data type, or any other metadata attribute. Once you have found the data asset you are looking for, you can use the Data Catalog to view its metadata, access the data itself, or perform other actions, such as creating reports or creating data pipelines.
