Описание: This book provides detailed guidance around architecting and deploying Power BI reporting solutions, including help and best practices for sharing and security. You’ll find chapters on dataflows, shared datasets, composite model and DirectQuery connections to Power BI datasets, deployment pipelines, XMLA endpoints, and many other important features related to the overall Power BI architecture that are new since the first edition. You will gain an understanding of what functionality each of the Power BI components provide (such as Dataflow, Shared Dataset, Datamart, thin reports, and paginated reports), so that you can make an informed decision about what components to use in your solution. You will get to know the pros and cons of each component, and how they all work together within the larger Power BI architecture. Commonly encountered problems you will learn to handle include content unexpectedly changing while users are in the process of creating reports and building analyses, methods of sharing analyses that don’t cover all the requirements of your business or organization, and inconsistent security models. Detailed examples help you to understand and choose from among the different methods available for sharing and securing Power BI content so that only intended recipients can see it. The knowledge provided in this book will allow you to choose an architecture and deployment model that suits the needs of your organization. It will also help ensure that you do not spend your time maintaining your solution, but on using it for its intended purpose: gaining business value from mining and analyzing your organization’s data. What You Will Learn * Architect Power BI solutions that are reliable and easy to maintain * Create development templates and structures in support of reusability * Set up and configure the Power BI gateway as a bridge between on-premises data sources and the Power BI cloud service * Select a suitable connection type—Live Connection, DirectQuery, Scheduled Refresh, or Composite Model—for your use case * Choose the right sharing method for how you are using Power BI in your organization * Create and manage environments for development, testing, and production * Secure your data using row-level and object-level security * Save money by choosing the right licensing plan Who This Book Is For Data analysts and developers who are building reporting solutions around Power BI, as well as architects and managers who are responsible for the big picture of how Power BI meshes with an organization’s other systems, including database and data warehouse systems.

Описание: 'This is an interesting and bittersweet biography. Elizabeth Alexander was a capable and energetic scientist, but circumstances meant that she was never able to settle down and develop her scientific career. The three years she spent in charge of the Operational Research Section of the Radar Development Laboratory in New Zealand was the only time that Elizabeth held a position of responsibility, and is a clear indication that, had she lived 50 years later, she would have been an effective science leader ... The book outlines the career of a remarkable scientist, and is a significant contribution to the history of several different areas of science. 'Scoop Review of BooksMany women scientists, particularly those who did crucial work in two world wars, have disappeared from history. Until they are written back in, the history of science will continue to remain unbalanced. This book tells the story of Elizabeth Alexander, a pioneering scientist who changed thinking in geology and radio astronomy during WWII and its aftermath.Building on an unpublished diary, recently declassified government records and archive material adding considerably to knowledge about radar developments in the Pacific in WWII, this book also contextualises Elizabeth's academic life in Singapore before the war, and the country's educational and physical reconstruction after it as it moved towards independence.This unique story is a must-read for readers interested in scientific, social and military history during the WWII, historians of geology, radar, as well as scientific biographies.Related Link(s)
