How do you relate tables?
You can relate the data present in multiple tables by using the concept of Foreign Keys. for example if we have an employee database that contains various details of an employee scattered in multiple tables, one column in each table can be used to logically group the data in all these tables. For example, the employee number column in each of these tables can be used to relate the data present in these tables.
