Which feature enables tracking of metadata for each dataset, including a reference to the schema?

The feature that enables tracking of metadata for each dataset, including a reference to the schema, is the Catalog. The Catalog serves as a repository that allows users to view, manage, and track datasets within Adobe Experience Platform. It organizes datasets and associated metadata, making it easier to access information about how data is structured and linked to its corresponding schema. This functionality is crucial for ensuring data governance and facilitating data discovery, which enhance the overall management of data in an analytics context.

Other features, while important in their respective domains, do not specifically cater to the metadata tracking of datasets. Data Mapping is more focused on how data elements correlate between different systems or formats. The Identity Service is primarily concerned with linking individual identities across different platforms and managing user profiles. Data Warehousing deals with storage and the aggregation of data for analysis but does not focus on tracking metadata related to schemas as comprehensively as the Catalog does.
