A relational database comprises of tables, some of which are related by
common
columns. for example there are two tables employee and dept. They are
joined by
a common column "dept_no".
Employee: Dept: -------------- -------- name dept_no address dept_name phone dept_desc
dept_no
dept_no is a foreign key to employee table and is a primary key to dept table.
Let me know if you have questions,
