Table merging is a fundamental operation in database management and data analysis, where multiple tables are combined to form a unified structure. Using standard functions in programming languages like SQL, Python, or R simplifies the process of merging tables efficiently. This paper explores various methods for merging tables using standard functions, focusing on SQL joins (INNER JOIN, LEFT JOIN, RIGHT JOIN, FULL JOIN) and the use of functions in Python (such as pandas merge()) and R. The article discusses the significance of these methods in relational databases and data manipulation tasks, highlighting the importance of data integrity, performance, and efficient query execution. Additionally, the paper addresses common challenges, such as handling missing data, managing large datasets, and ensuring accuracy during the merge process.
