This module introduces Power BI Desktop, a powerful tool for interactive data analysis and visualization. Its core objective is to teach users how to acquire data from various external sources and create insightful, dynamic reports. The course covers importing data from external Excel text files (e.g., government open data platforms), external web data (e.g., Wikipedia Olympic data), and Access databases. Key steps emphasized include data transformation (e.g., correcting member IDs) and establishing correct data relationships between tables. Users learn to create diverse interactive visualizations, such as cross-analysis filters, grouped bar charts, pie charts, line charts, and card visuals. A significant feature highlighted is the interactive nature of dashboards, where selecting an element in one visual instantly updates all linked charts. Proficiency in BI tools like Power BI is increasingly a fundamental requirement for many job roles, aiding in the analysis of phenomena, customer behavior, and the discovery of business insights. Installation of the Power BI Desktop application is a prerequisite.
