Solution
The data manipulation command that combines records from one or more tables is called JOIN. In relational database management systems, a JOIN operation is crucial for querying data across multiple tables, allowing users to access related data efficiently. The JOINS are typically utilized based on relationships defined by foreign keys in databases. There are different types of JOINs, including INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN, each serving specific purposes in how data is retrieved.
To clarify further, when you want to view data that exists in two or more tables, you use JOIN to merge those tables based on a related column that they share. For example, if you have two tables - "Employees" and "Departments" - you can join them using a common column such as "DepartmentID" to obtain a comprehensive view of employee information along with their respective department details.
