Sommario/riassunto

Develop powerful data models that bind data from disparate sources into a coherent whole. Then extend your data models using DAX–the query language that underpins Power BI–to create reusable measures to deliver finely-crafted custom calculations in your dashboards. This book starts off teaching you how to define and enhance the core structures of your data model to make it a true semantic layer that transforms complex data into familiar business terms. You’ll learn how to create calculated columns to solve basic analytical challenges. Then you’ll move up to mastering DAX measures to finely slice and dice your data. The book also shows how to handle temporal analysis in Power BI



using a Date dimension. You will see how DAX Time Intelligence functions can simplify your analysis of data over time. Finally, the book shows how to extend DAX to filter and calculate datasets and develop DAX table functions and variables to handle complex queries. What You Will Learn Create clear and efficient data models that support in-depth analytics Define core attributes such as data types and standardized formatting consistently throughout a data model Define cross-filtering settings to enhance the data model Make use of DAX to create calculated columns and custom tables Extend your data model with custom calculations and reusable measures using DAX Perform time-based analysis using a Date dimension and Time Intelligence functions.

Sommario/riassunto

Eating Out, first published in 2000, is a fascinating study of the consumption of food outside the home, based on extensive original research carried out in England in the 1990s. Reflecting the explosion of interest in food, ranging from food scares to the national obsession with celebrity chefs, the practice of eating out has increased dramatically over recent years. Through surveys and intensive interviews, the authors have collected a wealth of information into people's attitudes towards, and expectations of, eating out as a form of entertainment and an expression of taste and status. Amongst other topics they examine social inequalities in access to eating out, social distinction, interactions between customers and staff, and the economic and social implications of the practice. Eating Out will be a valuable resource to academics, advanced students and practitioners in the sociology of consumption, cultural studies, social anthropology, tourism and hospitality, home economics, marketing, and the general reader.
