Map a database schema for this ER model. You are free to make assumptions about any information that is not present as long as they don$$t contradict the model.

You will not need to use SQL data definitions for this, instead use the form R$($a$,$b$,$c$),$ where R is the name of the relation and a$,$ b and c represent attributes, use underline in the text editor to display primary keys and italics for foreign keys, e$.$g$.$ a foreign key that is also a primary key should be italic and underlined.

For each step of mapping provide justification and the resulting relations.
