Use the normalization rules such as first normal form, second normal form, and third normal form to achieve this. Create a Logical Model: Create a detailed data model that represents the entities, attributes, and relationships identified in step 1. As with the conceptual model, use standard ...
Primary Key, as it can't have null values and is singular per table. 8 Are both keys essential for normalization? While not the sole criteria, they are crucial for achieving higher normalization forms. 7 How does a DBMS enforce uniqueness? Through the constraints of Primary and Unique Keys,...
