Join

Definitions

1. A relational database operation that combines rows from two or more tables based on a related column or join condition. Different join types such as INNER, LEFT, RIGHT, and FULL determine which unmatched rows are kept in the result set.

   In plain English: It is a database operation that merges related information from different tables into one result.

   Example: "You need a join between orders and customers, otherwise that dashboard can't group revenue by region."
