Joining

Joining refers to the process of combining two or more datasets into a single dataset. This is a common operation in data science and artificial intelligence, as it allows analysts to combine data from multiple sources to gain a more complete understanding of a particular phenomenon. Joining can be performed using a variety of techniques, including inner joins, outer joins, left joins, and right joins. Inner joins only include records that have matching values in both datasets, while outer joins include all records from both datasets, even if there are no matching values. Left joins include all records from the left dataset and matching records from the right dataset, while right joins include all records from the right dataset and matching records from the left dataset.
