Activity 6: Normalizing Denormalized Data Using Excel

Objective:

Normalize 5 denormalized datasets by splitting them into multiple tables in an Excel workbook. Each dataset should be organized to reduce redundancy and follow database normalization rules.

Create an Excel Workbook with 5 Sheets

1. Open Microsoft Excel.

2. Create a new workbook.

Rename each sheet:

• Sheet 1: employeeData

• Sheet 2: studentData

• Sheet 3: productData

• Sheet 4: orderData

• Sheet 5: salesData

I populated each sheet with the denormalized data from the provided datasets:

Populate Sheets with Denormalized Data

Identifying Key Entities

I analyzed each dataset and identified repeating entities products. By recognizing these entities, I was able to split the data into multiple related tables to eliminate redundancy.

Each dataset is denormalized. Below is an example:

employeeData:

studentData:

productData:

orderData:

salesData:
