Description: Natural Join is a type of operation in relational databases that allows combining two or more tables based on common attributes, that is, columns that have the same name and data type. This operation is fundamental in the context of data engineering, as it facilitates the integration and analysis of information scattered across different tables. Natural Join is characterized by eliminating duplicate columns in the results, meaning that if there are identical columns in the combined tables, only one will be displayed in the final result. This property is especially useful for maintaining data integrity and clarity. Additionally, Natural Join is based on the equality of the values of the common columns, allowing for a logical and coherent combination of information. In terms of performance, this operation can be more efficient than other forms of join, as it reduces the amount of data processed by eliminating duplicate columns from the outset. In summary, Natural Join is a powerful tool in data engineering that allows analysts and developers to work with datasets more effectively and organized.
