دانلود کتاب Microsoft Power BI جهت آزمون PL-300

Exam PL-300 focuses on using Microsoft Power BI for data analysis. About one-fourth of the exam covers data preparation, which includes getting data from different data sources, as well as cleaning, transforming, and loading the data. Approximately one-third of the questions are related to data modeling: designing, developing, and optimizing a data model. Another one-third of the book covers the skills necessary to visualize and analyze data, such as creating reports and dashboards, as well as performing advanced analysis. The remainder of the book discusses how to manage datasets and workspaces in the Power BI service. This exam is intended for data analysts, business intelligence professionals, and report creators who are seeking to validate their skills and knowledge in analyzing data with Power BI. Candidates should be familiar with how to get, model, and visualize data in Power BI Desktop, as well as share reports with other people. This book covers every major topic area found on the exam, but it does not cover every exam question. Only the Microsoft exam team has access to the exam questions, and Microsoft regularly adds new questions to the exam, making it impossible to cover specific questions. You should consider this book a supplement to your relevant real-world experience and other study materials.
