Database Design

Before an Essential Oil product is marketed, testing is carried out based on the production batch from any essential oil. This is done to maintain the quality and content of the existing constituents in essential oils. Where the Test Percentage Content must reach the Minimum standard Percentage Content for each constituent. If there is one type of constituent that does not fulfill minimum standard, the batch will not be marketed because it does not meet the standard quality.

1. If recording the results of each testing process is still done manually,
according to you please explain which approach fits between Centralized and View Integration for gathering requirements.

2. What Fact Finding Methods you will choose to get
information related to the development of a database system to record the testing process, and explain the reasons for choosing.

3. Create 1-NF, 2-NF, 3-NF Normalization for the available forms.

4. Make an ERD (Entitiy Relationship Diagram) based on the results of Normalization 3-NF.

5. Develop the ERD that you create to implement Generalization / Specialization.
