How to fill out data model normal forms

1. To fill out data model normal forms, follow these steps: 1. Identify the functional dependencies in your dataset. Functional dependencies refer to the relationships between attributes in the dataset. 2. Remove any partial dependencies by creating separate tables for attributes that depend on only part of the primary key. 3. Eliminate any transitive dependencies by splitting the table into multiple tables, each with a distinct set of attributes. 4. Normalize the tables by ensuring that each table has a single purpose and does not contain redundant or duplicate data. 5. Apply the normalization rules (first normal form, second normal form, third normal form, etc.) to ensure the data is organized efficiently. 6. Validate the normalized data model to ensure it meets the necessary requirements for data integrity and efficiency. 7. Iterate and refine the data model as needed based on feedback and additional analysis.
