توضیحات کتاب
DAX با استخراج کلید یک مزیت اضافی ارائه می‌کند. اطلاعات از داده هایی که قبلاً در مدل شما وجود دارد. این کتاب آشپزی پر از نمونه‌هایی از محاسبات عملی و واقعی با معیارهای کسب‌وکار و شاخص‌های کلیدی عملکرد است، راه‌حل‌هایی را ارائه می‌کند که می‌توانید برای نیازهای تجزیه و تحلیل کسب‌وکار خود به کار ببرید.
شما یاد خواهید گرفت که عبارات و توابع مختلف DAX بنویسید تا بفهمید که کوئری های DAX چگونه کار می کنند. این کتاب همچنین بخش‌هایی را در مورد تاریخ، زمان و مدت پوشش می‌دهد تا به شما کمک کند با روزهای کاری، مناطق زمانی و شیفت‌ها مقابله کنید. سپس خواهید فهمید که چگونه می توانید متن و اعداد را برای ایجاد عناوین و رتبه های پویا دستکاری کنید و با مجموع اندازه گیری ها مقابله کنید. بعداً، معیارهای تجاری رایج برای امور مالی، مشتریان، کارمندان و پروژه‌ها را بررسی خواهید کرد. این کتاب همچنین به شما نشان می دهد که چگونه معیارهای رایج صنعت مانند روزهای عرضه، میانگین زمان بین خرابی، زمان چرخه سفارش و اثربخشی کلی تجهیزات را پیاده سازی کنید. در فصل‌های پایانی، استفاده از فرمول‌های آماری برای کوواریانس، کشیدگی و چولگی را یاد خواهید گرفت. در نهایت، الگوهای پیشرفته DAX را برای درون یابی، جمع‌کننده‌های معکوس، برش‌دهنده‌های معکوس و حتی پیش‌بینی با ضریب همبستگی غیرفصلی بررسی خواهید کرد.
در پایان این کتاب، مهارت‌های لازم برای استفاده از قابلیت و انعطاف‌پذیری DAX در هوش تجاری و تجزیه و تحلیل داده‌ها را خواهید داشت.
آنچه خواهید آموخت
- درک نحوه ایجاد محاسبات مشترک برای تاریخ، زمان و مدت زمان
- ایجاد شاخص های کلیدی عملکرد (KPI) و سایر محاسبات تجاری
- توسعه محاسبات کلی DAX با متن و اعداد
- کشف ایده های جدید و تکنیک های صرفه جویی در زمان برای محاسبات و مدل های بهتر

- Solve business issues with Microsoft Excel, Power BI, and SQL Server using DAX queries
Book Description
DAX provides an extra edge by extracting key information from the data that is already present in your model. Filled with examples of practical, real-world calculations geared toward business metrics and key performance indicators, this cookbook features solutions that you can apply for your own business analysis needs.
You'll learn to write various DAX expressions and functions to understand how DAX queries work. The book also covers sections on dates, time, and duration to help you deal with working days, time zones, and shifts. You'll then discover how to manipulate text and numbers to create dynamic titles and ranks, and deal with measure totals. Later, you'll explore common business metrics for finance, customers, employees, and projects. The book will also show you how to implement common industry metrics such as days of supply, mean time between failure, order cycle time and overall equipment effectiveness. In the concluding chapters, you'll learn to apply statistical formulas for covariance, kurtosis, and skewness. Finally, you'll explore advanced DAX patterns for interpolation, inverse aggregators, inverse slicers, and even forecasting with a deseasonalized correlation coefficient.
By the end of this book, you'll have the skills you need to use DAX's functionality and flexibility in business intelligence and data analytics.
What you will learn
- Understand how to create common calculations for dates, time, and duration
- Create key performance indicators (KPIs) and other business calculations
- Develop general DAX calculations that deal with text and numbers
- Discover new ideas and time-saving techniques for better calculations and models
- Perform advanced DAX calculations for solving statistical measures and other mathematical formulas
- Handle errors in DAX and learn how to debug DAX calculations
- Understand how to optimize your data models
Who this book is for
Business users, BI developers, data analysts, and SQL users who are looking for solutions to the challenges faced while solving analytical operations using DAX techniques and patterns will find this book useful. Basic knowledge of the DAX language and Microsoft services is mandatory.
