Which statement describes the typical content of a data catalog?

A data catalog is designed to provide a centralized repository that efficiently organizes and describes data assets within an organization. The typical content of a data catalog includes a collection of various data sources along with their associated metadata—this encompasses information such as data types, source systems, and any relevant context about how the data can be used. Additionally, usage documentation is often part of a data catalog to guide users on how to adequately access and utilize the data for analysis, reporting, or other purposes.

This comprehensive approach aids in data governance and enhances data discovery, making it easier for users to find the right data for their needs while understanding the structure and context in which that data can be applied. The inclusion of metadata helps bridge the gap between raw data and actionable insights, thereby supporting better decision-making processes.

In contrast, other options do not capture the multifaceted nature of a data catalog. A comprehensive database of operational data would focus solely on operational datasets without considering their descriptive aspects. Limiting the catalog to only large datasets for machine learning overlooks the broader organizational data landscape and utility of smaller datasets. A report summarizing data processing speeds does not relate to the curational and descriptive elements that a data catalog aims to provide.
