Which way to reach Data 360 data from outside it: Data Explorer and Query Editor, the SQL Query APIs (async paging, caching, workloadName), JDBC, Python and the Connect API for Apex, companion versus standard org connections, and data shares between Data 360 orgs.

- Certification: Salesforce Data 360 Consultant
- Exam section: Data Enhancements, Sharing, and Analysis
- Study guide: https://www.certifyforce.com/study-guide/data-360-consultant

**Official exam objective:**

> Explain how to reference Data 360 data from other systems.

## What the exam expects

- Pick the retrieval method from who is asking: an admin exploring visually, an external app sending SQL over REST, a Java or Python program, or Apex inside the org.
- Run a large query through the SQL Query APIs correctly: queryId, polling, paging with rowLimit and offset, caching and workloadName.
- Explain the home org, standard Salesforce CRM connections and Data Cloud One companion connections, and what each lets a connected org do.
- Share Data 360 objects with another Data 360 org and predict how they land and who pays.

Key terms: **home org** (the org Data 360 is provisioned on), **companion connection** (bidirectional connection that syncs unified metadata to a CRM org), **SQL Query APIs** (Connect API endpoints that run Data 360 SQL), **data share target** (the connection to the receiving Data 360 org).
