1NF to 2NF
- Identify the primary key for the 1NF relation.
- Identify the functional dependencies in the relation.
- If partial dependencies exist on the primary key remove them by placing them in a new relation along with a copy of their determinant. (The part of the primary key they depend on)
Step1:Write Each Key Component on a Separate Line.
- Write each key component on separate line, then write original (composite) key on last line.
- Each component will become key on last line
Step2:Assign Corresponding Dependent Attributes
- Determine those attributes that are dependent on other attributes
- At this point most anomalies have been eliminated
