Blog: Unlocking Insights from Retail Data
Retail businesses generate vast amounts of data daily, and within this data lies the key to understanding customer behavior, optimizing operations, and driving revenue growth. For this exercise, we will explore a dataset containing retail transaction data spanning two time periods: 2009-2010 and 2010-2011.
This dataset includes information such as:
• Invoice Number: A unique identifier for each transaction.
• Stock Code: Unique codes for each product sold.
• Description: Detailed information about the products.
• Quantity: The number of items purchased in each transaction.
• Invoice Date: The date and time of the transaction.
• Unit Price: Price per unit of each product.
• Customer ID: An anonymized identifier for each customer.
• Country: The country where the transaction took place.
