STUDENT PROJECTS: Drawing an EER diagram and creating an object-
relational database for the Student Projects .

Step 8.1: Modify the ER diagram and draw an EER diagram to represent the enterprise.
Be sure to identify relationship participation and cardinality constraints using (min,max)
notation. Identify any weak entity sets. Use generalization and union as necessary to
express class relationships, adding appropriate constraint notation.

Step 8.2 Map the EER diagram to an Object-Relational Model

Step 8.3 Write the DDL to create the object-relational database, using Oracle syntax or
the syntax of the object-relational database management system you are using, and
execute the commands.

Step 8.4 Insert several records in each table.

Step 8.4 Write five DML commands for the new database, illustrating differences from
the strictly relational DML.
