Given the E-R diagram shown above, give a database schema (i.e. list of relations) for it. The keys of each entity are shown in uppercase letters. Double lines indicate total participation; single lines, partial participation. Double oval attributes are multivalued. Make sure to give the keys for each relation (primary and foreign) and all integrity constraints as follows: after each table schema, write PK: followed by the primary key, and FK:... REFERENCES ... for each foreign key.
