**Unlocking Efficient SQL Data Analysis with CTEs**

Common Table Expressions (CTEs) are a powerful tool in SQL that simplifies complex data analysis, making it easier to manage and interpret. By breaking down multi-step transformations into modular pieces, CTEs improve query readability and performance. They can be used for recursive queries, data cleaning, and transformation, allowing for more efficient data analysis.
