Inner Joins
Inner join is a type of join operation in relational databases that returns only the matching rows between two tables. It combines rows from two or more tables based on a related column between them. The result set contains only the rows that have matching values in both tables. Inner join is commonly used in data analysis and data mining to combine data from different sources and extract meaningful insights. It helps to eliminate the rows that do not have matching values, which reduces the size of the result set and improves the performance of the query. Inner join is one of the most frequently used join operations in SQL and other relational database management systems.
