Download or read book Power BI DAX Simplified written by Reza Rad and published by RADACAD Systems Limited. This book was released on 2021-07-18 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: DAX is the language of data analysis in Microsoft Power BI, Azure Analysis Services, and Excel Power Pivot. DAX is a powerful language that can quickly empower you to analyze year-over-year or rolling 12 months calculations. It is rare to find an analytics solution using Microsoft technologies (especially Power BI) that doesn’t require some calculations to be written by DAX. As a Power BI (or Microsoft BI) developer, it is essential to learn this language and master it. Learning a language is not just learning the structure and functions. It is learning how, where, and when to use it so that you can solve real-world problems with it. In my training and consulting experience on Power BI, I realized that DAX is the weak point for many Power BI users. DAX itself is not a complex language. It is merely a language of expression. The complexity of learning DAX is not the formula or the functions. It is how to use it in real-world scenarios and how it performs on a dataset or visual. I have been writing many blogs about DAX for many years. My blog articles are all coming from my experience working with Power BI. I found it helpful to compile them all in a book. Because my blog articles practically explain things, I thought it better to title it as a practical way of learning DAX by examples. Indeed, there are books, articles, and Microsoft documentation on how each function works where and how. However, learning these through an example would bring a new way of understanding it. A good analytics solution is a combined outcome of a good data model, good data preparation, and good analytics and calculations. I have written another book about the Basics of modeling in Power BI. This book is covering the calculation and DAX aspects of it. This book is for you if you are building a Power BI solution. Even if you are just visualizing the data, calculations are an essential part of analytics. You do need to have the calculation ready before visualizing it. This is not a book to explain every single function in DAX. The approach in this book is to have practical examples. Every chapter is based on real-world examples of using a combination of functions to solve a challenge. You can start from any chapter and finish at any chapter. The order of chapters suggested in this book is just a guideline to help you have a smooth flow of topics. Each chapter can be read without needing other chapters. Examples of this book are designed in a way that you can use the learning straight away in your Power BI file.

This book was released on 2011-06-28 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: After the Empire’s bloody purge of the Jedi, one lone Knight still fights for those who cannot, unaware that he’s about to be swept into a cataclysmic battle against the Master of Darkness himself. Throughout the galaxy, a captured Jedi is a dead Jedi, even in Coruscant’s most foul subterranean slums, where Jedi Knight Jax Pavan champions the causes of the oppressed with the help of hard-nosed reporter Den Dhur and the wisecracking droid I-5YQ. But Jax is also involved in another struggle–to unlock the secrets of his father’s death and his own past. While Jax believes that I-5YQ holds some of those answers, he never imagines that the truth could be shocking enough to catapult him to the frontlines of a plot to kill Emperor Palpatine. Worse yet, Darth Vader’s relentless search for Jax is about to end . . . in triumph. The future looming over the valiant Jedi and his staunch pals promises to be dark and brief, because there’s no secret whatsoever about the harshest truth of all: Few indeed are those who tangle with Darth Vader . . . and live to tell the tale. Features a bonus section following the novel that includes a primer on the Star Wars expanded universe, and over half a dozen excerpts from some of the most popular Star Wars books of the last thirty years!

Download or read book Territorial Cohesion in Rural Europe written by Andrew Copus and published by Routledge. This book was released on 2014-08-13 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reflects on how the economies, social characteristics, ways of life and global relationships of rural areas of Europe have changed in recent years. This reveals a need to refresh the concepts we use to understand, measure and describe rural communities and their development potential. This book argues that Europe has 'outgrown' many of the stereotypes usually associated with it, with substantial implications for European Rural Policy. Rural structural change and its evolving geography are portrayed through regional typologies and the concept of the New Rural Economy. Demographic change, migration, business networks and agricultural restructuring are each explored in greater detail. Implications for equality and social exclusion, and recent developments in the field of governance are also considered. Despite being a subject of active debate, interventions in the fields of rural and regional development have failed to adapt to changing realities and have become increasingly polarized. This book argues that rural/regional policy needs to evolve in order to address the current complex reality, partially reformulating territorial or place-based approaches, and the New Rural Paradigm, following a set of principles termed ‘Rural Cohesion Policy’.
