Summary  
This chapter covers combining multiple tables by appending rows into a single dataset and then integrating related data via join operations (e.g., left joins), with transformation steps applied to maintain a consistent schema.  

General domain of usage  
Data analysis

Start by combining data from two separate years using the **Append Queries** feature, which merges datasets into a **single table**. After that, apply various transformations to clean and prepare the data for analysis. Finally, **merge** the cost table dataset using a **left join** to ensure that all records are properly integrated. This process results in a comprehensive and well-structured dataset, ready for accurate and efficient analysis.
