Normalization

Normalization is the process of eliminating redundancy in a database by organizing the data into several smaller tables. The large tables are normalized (converted) into smaller tables by using normalization rules, so that a database administrator can easily handle them. It also eliminates insertion, deletion, and update anomalies.

The image contains text that provides the following instructions for modifying dependency diagrams:

b) Modify the dependency diagrams you created in part (a) to produce a collection of dependency diagrams that are all in 3NF. *(Hint: One of your dependency diagrams will be in 3NF, but not in BCNF.)*

c) Modify the dependency diagrams in part (b) to produce a collection of dependency diagrams that are all in 3NF and BCNF.

**Q2. Use the dependency diagram shown below to work the following problems.**

**Initial dependency diagram:**

[Diagram Description]
- The diagram consists of seven elements labeled A, B, C, D, E, F, and G.
- A and B are grouped together in an orange rectangle with A having an arrow pointing to B.
- The elements C, D, E, F, and G are grouped in a blue rectangle.
- There are arrows showing dependencies:
- A points to B, C, D, E, F, and G.
- B points to C and D.
- D points to E.
- E points to F and G.

**a) Break up the dependency diagram above to create two new dependency diagrams, one in 3NF and one in 2NF.**

Task #1 – Identification of dependencies We learned about two types of functional dependencies, Partial Dependency and Transitive Dependency, and they are critical clues for the identification of tables. In this task, we will practice how to identify the two types of dependencies, so that we can improve the results to new tables. Below is a list of attributes of a dataset. However, the attributes still have some functional dependencies, which means you can create more tables by separating some field(s). Order_ No Product_ No Product_ Description Product_ UnitPrice Customer_No Customer_ Phone Customer_ Address Order_ Date Shipping_ Address Order_ Qty Which partial dependency does this dataset have? Identify the partial dependency using the format in the example below. Example) Partial Dependencies: (ProjectNum ? Proj_Name) (Emp_Num ? Emp_Name, Job_Class) Then, which transitive dependencies does this dataset have? Identify the transitive dependencies…
