How to fill out 2nf 2nd normal form

How to fill out 2NF 2nd Normal Form:

1. Identify the functional dependencies: Analyze the relationship between the attributes in your database table to determine the functional dependencies. This involves understanding how changes in one attribute value affect other attribute values.
2. Eliminate partial dependencies: Partial dependencies occur when a non-key attribute depends on only a portion of the primary key. To eliminate partial dependencies, break the table into two separate tables, each with its own primary key.
3. Create new tables: Once you have identified and removed partial dependencies, create additional tables to hold the attributes that were moved out from the original table. These new tables should have their own primary keys.
4. Establish relationships between tables: Establish relationships between the original table and the newly created tables using foreign keys. This ensures data integrity and allows for easy retrieval of related information.
