How to fill out Relation Normalization

1. Identify all the attributes of the relation.
2. Group the attributes based on their dependencies.
3. Remove any repeating groups and ensure that each set of attributes is dependent on the primary key.
4. Create separate relations for sets of attributes that are only partially dependent on a composite key.
5. Eliminate transitive dependencies by creating new relations for dependent attributes that are not directly tied to the primary key.
6. Conduct a final review to ensure that the new relations maintain all necessary dependencies and constraints.

2. Software developers working on applications that require efficient data storage.
3. Data analysts needing to ensure data integrity and reduce redundancy.
