Join Operation
Join operation is a technique used in relational databases to combine data from two or more tables based on a related column between them. The join operation is performed by matching the values in the specified columns of the tables and returning a new table that contains all the columns from both tables. There are different types of join operations such as inner join, left join, right join, and full outer join. Inner join returns only the matching rows from both tables, left join returns all the rows from the left table and matching rows from the right table, right join returns all the rows from the right table and matching rows from the left table, and full outer join returns all the rows from both tables. Join operation is a fundamental concept in data science and artificial intelligence as it allows combining data from multiple sources to perform analysis and gain insights.
