Databricks - Data Analyst Associate Study Guide

2: Managing Data

This chapter is the working analyst's playbook for daily data stewardship on Databricks. It shows how to discover and query certified datasets in Unity Catalog, how to tag assets and read lineage in Catalog Explorer to answer "who uses this and where does it come from," and how to write practitioner-grade SQL that removes invalid rows, resolves NULLs, and hardens raw data into trustworthy Gold-layer inputs.
