2. Following the process Logical modeling, create a Relational Model in 3rd Normal Form based on the ER Model provided (below)

Answer 1

Hello! The image isn't coming through but here is some general guidance. Hopefully it will be helpful:

Start by analyzing your ER Model. Identify all entities, their attributes, primary keys, and the relationships between them (one-to-one, one-to-many, many-to-many).

Then convert to a Relational Model. Each entity becomes a table. One-to-many relationships are handled by placing the primary key of the "one" side as a foreign key in the "many" side table. Many-to-many relationships get their own junction table holding both foreign keys.

Finally, normalize to 3NF by working through each level:

1. 1NF: All values are atomic, no repeating groups
2. 2NF: Every non-key attribute depends on the full primary key, not just part of it
3. 3NF: No non-key attribute depends on another non-key attribute (remove transitive dependencies)
