Analytics Hub Data Exchange Platform

Analytics Hub is a data exchange platform that enables sharing of data and insights.
The core components of Analytics Hub are:

• Analytics Hub Publisher: Publishes the data and share data at real time.

• Listings: Enables sharing of data without replicating the shared data.

• Analytics Hub Subscriber: Discover the data one is looking for, can combine data with existing datasets and leverage Bigquery for various analytics. When subscribed to a listing a linked dataset gets created in the project.

• Analytics Hub Viewer: One can browse through the datasets that are accessible in Analytics Hub.

• Analytics Hub Administrator: Create data exchange enabling data sharing. Grant permission to data publishers and subscribers to access these data exchanges.

Architecture Flow:
