Merging


Merging is the process of combining two or more datasets into a single dataset. This process is commonly used in data science and artificial intelligence to combine data from different sources to gain a more comprehensive understanding of a particular problem or phenomenon. Merging can be done using various techniques such as inner join, outer join, left join, and right join. Inner join combines only the matching records from both datasets, while outer join combines all records from both datasets and fills in missing values with null. Left join combines all records from the left dataset and matching records from the right dataset, while right join combines all records from the right dataset and matching records from the left dataset. Merging is an important step in data preprocessing and is often used in machine learning algorithms to train models on large datasets.
