Data cataloging is the process of creating a detailed inventory of all digital assets. It is a data stewardship activity that helps the data consumer understand and retrieve information.

Modern data catalogs are a vital component of data stewardship. They allow data consumers to discover and access related data across multiple databases.

Today’s modern data teams include analysts, data scientists, and product managers. A data catalog is used by all of these teams.
The modern data catalog combines the information collected by a data inventory with a fresh business context. This ensures that all users have access to the data they need.

A modern data catalog can be either on-premises or cloud-based. Often, it’s integrated with a data governance software solution. These tools help meet regulatory compliance requirements.

Modern data catalogs also provide granular control over data. Users can access data from any source, including unstructured data. For example, a data engineer may want to create a consolidated customer data set.

A modern data catalog is also a great tool for data profiling. It provides the consumer with a detailed summary of data and its quality. It can be used to examine data sources by context, such as the minimum value for a column, the number of tables, or the number of files.

A data catalog can also be a repository for user-generated metadata. Some examples of crowdsourced metadata include tips, techniques, and knowledge about groups.

When a digital object is moved, metadata travels with it. It is used to provide crucial context for information and can also help determine its structure and relationships.
