An employee has only one jobcode but a jobcode can be held


Question: Use the database shown in Figure

Note that the database is composed of four tables that reflect these relationships:

• An EMPLOYEE has only one JOB_CODE, but a JOB_CODE can be held by many EMPLOYEEs.

• An EMPLOYEE can participate in many PLANs, and any PLAN can be assigned to many EMPLOYEEs.

Note also that the M:N relationship has been broken down into two 1:M relationships for which the BENEFIT table serves as the composite or bridge entity

Create the relational diagram to show the relationships among EMPLOYEE, BENEFIT, JOB, and PLAN.
