Mentoring and assistance for database design in Oracle SQL Database Modeler

We have an ERD and a conceptual diagram. Entities and attributes are generally correct. We need someone to check if the relationships between entities are correct and/or suggest changes.

After that we need to handle the 1:1, M:N relationships (provide solutions AND EXPLANATION of how you handled these relationships).

When we have the solutions for relationships, we need the design of logical diagram (no datatypes, or foreign keys here, only primary keys).

Next step is normalization to 3NF. In each step 0NF->1NF, 1NF->2NF, 2NF->3NF we need to check all entities and write(comment) what changed needed to be done and design the diagram of 3NF.

Then we determine the constraints and design the final fully attributed and normalized diagram in data modeler.

Project must be done in Oracle Data Modeler.
