Microsoft Power Bi Data Analyst Certification Companion: Preparation for Exam Pl-300 (Paperback)

Use this book to study for the PL-300 Microsoft Power BI Data Analyst exam. The book follows the "Skills Measured" outline provided by Microsoft to help focus your study. Each topic area from the outline corresponds to an area covered by the exam, and the book helps you build a good base of knowledge in each area. Each topic is presented with a blend of practical explanations, theory, and best practices.
Power BI is more than just the Power BI Desktop or the Power BI Service. It is two distinct applications and an online service that, together, enable business users to gather, shape, and analyze data to generate and present insights. This book clearly delineates the purpose of each component and explains the key concepts necessary to use each component effectively. Each chapter provides best practices and tips to help an inexperienced Power BI practitioner develop good habits that will support larger or more complex analyses.
Many business analysts come to Power BI with a wealth of experience in Excel and particularly with pivot tables. Some of this experience translates readily into Power BI concepts. This book leverages that overlap in skill sets to help seasoned Excel users overcome the initial learning curve in Power BI, but no prior knowledge of any kind is assumed, terminology is defined in non-technical language, and key concepts are explained using analogies and ideas from experiences common to any reader. After reading this book, you will have the background and capability to learn the skills and concepts necessary both to pass the PL-300 exam and become a confident Power BI practitioner.
What You Will Learn

• Create user-friendly, responsive reports with drill-throughs, bookmarks, and tool tips
• Construct a star schema with relationships, ensuring that your analysis will be both accurate and responsive

Who This Book Is For
Power BI users who are planning to take the PL-300 exam, Power BI users who want help studying the topic areas listed in Microsoft's outline for the PL-300 exam, and those who are not planning to take the exam but want to close any knowledge gaps they might have

使用這本書來準備 PL-300 Microsoft Power BI 資料分析師考試。本書遵循微軟提供的「技能評估」大綱，幫助你專注於學習的重點。大綱中的每個主題對應到考試中的一個範圍，本書幫助你在每個範圍建立扎實的知識基礎。每個主題都以實用解釋、理論和最佳實踐相結合的方式呈現。

Power BI 不僅僅是 Power BI Desktop 或 Power BI Service。它是兩個獨立的應用程式和一個在線服務，共同使業務使用者能夠收集、整理和分析數據以生成和呈現洞察。本書清楚地劃分了每個組件的用途，並解釋了使用每個組件所需的關鍵概念。每一章都提供最佳實踐和提示，以幫助沒有經驗的 Power BI 從業人員培養良好的習慣，以支持更大或更複雜的分析。

許多業務分析師在 Excel 中擁有豐富的經驗，特別是在樞紐分析表方面。這些經驗可以輕鬆轉化為 Power BI 的概念。本書利用這些技能重疊的部分，幫助熟練的 Excel 使用者克服在 Power BI 中的初始學習曲線，但不需要任何先備知識，術語以非技術性的語言進行定義，並使用類比和讀者共同經歷的想法來解釋關鍵概念。閱讀本書後，你將具備背景和能力，學習通過 PL-300 考試所需的技能和概念，並成為一名自信的 Power BI 從業人員。

你將學到什麼：
- 使用鑽取、書籤和工具提示創建用戶友好、響應式的報告
- 構建具有關聯性的星型模式，確保你的分析準確且響應迅速
- 將報告和數據集發布到 Power BI Service，使報告（和數據集）可以被你的同事查看和使用
