Join
Combining data from two or more database tables based on a related column.
Definition
Combining data from two or more database tables based on a related column. Joins are what make relational databases powerful — they let you connect related information stored in separate places.
Example
A 'students' table and a 'grades' table are separate, but both have a student_id column. A JOIN lets you combine them to see each student's name alongside their grades.
