Databricks - Data Analyst Associate Study Guide

4: Executing queries using Databricks SQL and Databricks SQL Warehouses

This chapter walks through the analyst's day-to-day query workflow on Databricks SQL: authoring and debugging queries with the Databricks Assistant, picking and sizing a SQL warehouse, joining Delta tables with federated foreign catalogs, choosing between streaming tables, materialized views, and dynamic views, aggregating and reshaping data with SQL, and creating unified managed and external tables in Unity Catalog. It also covers Delta Lake time travel for historical queries and rollback validation.
