Equi Join

An Equi Join is a type of database operation that combines data from two tables based on matching values in a specific column, called the key. Think of it like matching items from two lists where the key values are the same—such as connecting a list of employees with their corresponding departments using a department ID. This join retrieves combined records only when the key matches in both tables, allowing you to see related information together. It’s commonly used to build comprehensive views of data that are related through shared identifiers.
