Note: To draw the Relational Schema, you can use a computer-based graphic tool such as VISIO, Lucid Chart (lucidchart.com), Creately (creately.com), or Gliffy (gliffy.com).

Draw your Relational Schema based on the EER Diagram (conceptual data model) presented below. Your relations should be normalized to the third Normal form (3NF). Be sure to: use arrows from the foreign keys to their corresponding primary keys to show the referential integrity constraints; underline the primary key in every relation.
