Inner Join
Inner join is a type of join operation in relational databases that returns only the matching rows from both the tables involved in the join. It combines rows from two or more tables based on a related column between them. The result set of an inner join contains only the rows that have matching values in both tables. In other words, it returns the intersection of the two tables. Inner join is commonly used in data science and artificial intelligence applications to combine data from multiple sources and perform analysis on the combined data. It is a powerful tool for data integration and data cleansing, as it allows the user to filter out irrelevant data and focus on the relevant data.
