Data catalogs are a data inventory tool that enables users to easily connect and search data. They are often used by data scientists, data engineers, business analysts and other employees who work with data.
A data catalog helps users find and access data from any source, allowing them to build and maintain a comprehensive picture of all their data. It provides a centralized view of all databases and other data assets in the enterprise.
It is also a key element of data stewardship. Modern data catalogs can be used to assess the fitness of any data.
It includes administrative and descriptive metadata that describes the structure, content and interrelationships of digital objects. The process of creating metadata is a combination of human and technical activities.
It can be stored in a separate file or in a database system. Metadata is usually written in a human-readable format. This makes it easier for humans to understand the information.
When a digital object changes, the metadata changes as well. Some catalogs have special tools to convert the metadata into a more readable format.
Data catalogs can also help identify a person or entity. These metadata are important in determining the origin of the data. An analyst may want to know who is associated with a particular piece of data.
Today’s modern data catalogs are built on top of a knowledge graph. This allows all teams to have full democratic access. In addition, they are built with granular control.
