Union

In data science, union refers to the process of combining two or more datasets into a single dataset. This is typically done when the datasets have the same structure and can be concatenated vertically. The resulting dataset will have all the rows from each of the original datasets. The union operation is useful when working with large datasets that are split across multiple files or databases. It allows data scientists to combine the data into a single dataset that can be analyzed more easily. In addition, the union operation can be used to merge datasets that have different variables, but share a common identifier. This is known as a join operation.
