You are working as a junior data analyst supporting management at Olist, a Brazilian marketplace that connects sellers with customers and provides logistics support. Management wants better visibility into marketplace performance and has asked the analytics team to investigate five questions: - How is the marketplace performing? - What is driving sales performance? - How well is Olist delivering orders? - What is happening to customer satisfaction? - Where should management focus its attention? During Day 1, you connected to the nine Olist datasets, explored their contents, transformed and cleaned the data in Power Query, and loaded the prepared data into Power BI. Your work does not end with loading the data. In this activity, you will take ownership of the analysis by revisiting the business problem, investigating the structure of the data, attempting to build the data model, creating your first analytical measures, and exploring the data for meaningful patterns. You are not expected to get everything right. You are expected to make a genuine attempt, explain your reasoning, investigate problems, and document what you discover. Your goal is to move from simply having data to being able to use that data to answer a business question.
