Explanation of Solution
Normalization process:
The process used to minimize data redundancy and dependency in a relational
Steps of normalization process:
First, a primary key is identified and any repeating groups are identified (1NF). Second, any partial dependencies are eliminated (2NF). Third, any transitive dependencies are eliminated (3NF).
First-Normal Form (1NF):
- If a table does not contain any replicate fields or groups of fields then that model is called as first normal form.
- In this form, entities do not contain any single instance of the repeating variable.
- It means that the entities contain only one instance of the attributes, multi-valued attributes are neglected...
