Some of the latest SQL tricks every analyst should know include using window functions for running totals, rankings, and moving averages—these reduce complex queries into clean, efficient logic.

Many advanced topics are now part of Google data analytics certification courses because they help analysts work faster, cleaner, and more accurately with large datasets.
