Exploratory Data Analysis: Understanding all kinds of information that can be generated from this data, such that has a meaningful impact on the business. Since this is a transaction record of a business, the most important part of a business is sales, it's about how much profit can be generated and how can we use this information to increase sales in the future. Therefore, I use this to get as much information as possible regarding the sales information, such as countries that have more sales, time of day that has more sales, type of customer to target, which product has the greater sales at a certain time, etc.
