Storing the data

Different teams in your organization store customer and performance data in BigQuery. Each team must retain full control of the data it collects, be able to query data in its own projects, and exchange data with other teams. You need to implement an organization-wide solution while minimizing operational effort and cost. What should you do?

Explanation

BigQuery sharing through Analytics Hub uses a publish-and-subscribe model with zero-copy sharing. A publisher keeps its source data under its control, and a subscriber receives a read-only linked dataset in its own project that it can query. This avoids copying data and the associated storage, replication, and maintenance overhead.
