Using the database shown in Figure P$3\mathrm{.}1,$ the database is composed of four tables that reflect these relationships:

$-$ A JOB can be assigned to many EMPLOYEEs but one EMPLOYEE can be assigned to only one JOB$55.$

$-$ An EMPLOYEE can participate in many PLANs, and a PLAN can be assigned to many EMPLOYEEs.

$-$ M:N $($many to many$)$ relationship between EMPLOYEE and PLAN has been broken down into two $1$:M $($one to many$)$ relationships for which the BENEFIT table serves as the composite or bridge entity.

For each table in the database above, I identified the primary key and the foreign key$($s$)$ in the purple table provided. When the table does not have a foreign key, I wrote None in the assigned space provided. Now, all that has to be done is create a crow's foot to show the relationships among EMPLOYEE, BENEFIT, JOB, and PLAN.

Please let me know: what I am lacking in my creation of crow's foot?
