2. Begin with the 'Semantics of the Attributes' section. Here, clearly define the relationships between the attributes. Use straightforward and relevant examples to illustrate the meanings of each attribute, such as linking 'Student name' to 'USN No'.
3. Proceed to 'Reducing the Redundant Value in Tuples'. In this section, identify ways to minimize redundancy. Utilize grouped attributes to streamline your design, ensuring to illustrate through examples how stored information could be consolidated effectively.
4. Next, address 'Reducing Null Values in Tuples'. Define strategies to minimize NULL values within your design. Mention circumstances that lead to NULL values and propose methods to handle attributes that frequently contain NULL.
5. Move on to 'Disallowing Spurious Tuples'. Emphasize the importance of avoiding bad design that leads to erroneous results during JOIN operations. Discuss the 'lossless join' property and how to ensure it while designing relations.
6. In the 'Functional Dependency' section, elaborate on the constraints and relationships that govern data attributes. Clearly outline various functional dependencies and their significance in defining normal forms.
7. Continue with the section on 'Normal Forms'. Clearly explain the purpose of each normal form (1NF, 2NF, 3NF, BCNF, 4NF, and 5NF) and provide examples that illustrate how to achieve compliance with these forms in your relational schema.
8. After completing the informational sections, review your filled-out document for accuracy and completeness. Ensure all necessary examples are included and that you have adhered to the guidelines presented.
