Preparing the data

Congratulations! You have been hired as the new analyst for Acropolis Retail Ltd. and your first task for the company will be carrying out inventory analysis for the management team. You have been provided with the raw data files to start your work.

The first step in any analysis is doing a data check. In this exercise, you'll load the relevant data tables and determine if one of your tables contains any duplicates. If your data has duplicate rows, you might double-count stock items. This would even affect the results of your analysis.
