Relational Database

This document details the structure of two tables, EMP and DEPT, in a relational database setup. The EMP table includes employee records with attributes such as EMPNO (Employee Number), ENAME (Employee Name), and DEPTNO (Department Number) while the DEPT table comprises department information with DEPTNO, DNAME (Department Name), and LOC (Location). Together, they illustrate the relationships established through primary and foreign keys, demonstrating how employee records are linked to their respective departments.
