Step $1.$ Create a set of requirements that will be used to create the ER Diagram in Step $2.$

$1$

Step $2.$ Create an ER diagram $($using ERDPlus$)$ that contains at least five entities and at least four binary relationships. At least one of the relationships should be many to many. Show all attributes of all entities. Please draw the ER diagram!

Step $3.$ Map the ER diagram you created in Step $2$ into a relational schema containing the relations $($with their attributes$)$ and the referential integrity constraints $($i$.$e$.$ arrows pointing from foreign keys into their sources$).$ UselERDPlus to draw the mapped relational schema.
