In a particular ER schema, we have a one-to-many relationship type WORKS FOR between EMPLOYEE and DEPARTMENT. The EMPLOYEE entity type has five attributes: EID, Name, Address, Age, and Phone with EID as the key attribute. The DEPARTMENT entity type has three attributes: DeptID, DeptName, Location with DeptID as the key attribute. Note that every employee must work for a department and a department may have one or many employees.

Convert the above ER schema into relational schema(s). Note that you need also specify primary key and referential integrity constraints
