Class Introduction
This was a Power BI training class focused on teaching fundamental data modeling techniques to students and professionals. The instructor guided participants through downloading and installing the required dataset from TeamAcademy.click/dataset, explaining the importance of using the provided dataset to learn all Power BI capabilities before applying the skills to real-world data. The class covered three main concepts: metadata analysis using the Power Query Editor's column profile features, append queries for combining multiple tables or sheets vertically, and the combine function for mass processing multiple Excel files based on a defined template. Students practiced these techniques using the "Table vs Sheet" Excel workbook, learning how to extract data from tables rather than entire sheets, perform metadata analysis to understand data distribution, and combine multiple Excel files automatically from a folder. Several students experienced technical difficulties accessing the dataset or connecting to the shared resources, and the instructor provided individual support to help them resolve these issues.
