Overview of this book

Business Intelligence Semantic Models (BISM) is a technology that is designed to deliver analytical information to users through a variety of mechanisms that include model structure, definition, and design. This book demonstrates how to create BISM models so that information can be presented to users in an intuitive and easy-to-use format. Once the model is defined, we also show you how it can be managed and maintained so that the data in it remains current and secure. Microsoft Tabular Modeling Cookbook is an all-encompassing guide to developing, managing, creating, and using analytical models using the Business Intelligence Semantic Model (BISM). This title covers a range of modeling situations and common data analysis related problems to show you the techniques required to turn data into information using tabular modeling. Microsoft Tabular Modeling Cookbook examines three areas of tabular modeling: model development, model management and maintenance, and reporting. This book is a practical guide on how to develop semantic models and turn business data into information. It covers all phases of the model lifecycle from creation to administration and finally reporting. It also shows you how to create models which are designed to analyze data. All sections of BISM modeling from development to management and finally reporting are covered. The sections on development examine a wide range of techniques and tricks required to build models, including moving data into the model, structuring the model to manipulate the data, and finally the formulas required to answer common business questions; all of these are discussed in this book in detail. Finally, the book examines methods of reporting on the data within the model, including the creation of data-driven workbooks and reports for a powerful end user experience.

Restricting data with filters and where conditions


In the Using projection to combine data from different tables recipe, we stated that there is no WHERE clause in DAX. If this type of restriction is to be applied to a result set, it must be defined by a query, and this is the focus of this recipe. Here, we seek to answer the question:

Which customers had sales in 2008 and what was their sales value (for that year)?

Getting ready

The model used in this recipe is the sales data that has been used in this chapter (see the workbook Model.xlsx, which is available from online resources at http://www.packtpub.com).

How to do it…

This recipe examines two queries. Firstly, listing customers and their sales value in 2008, and secondly, listing customers that had sales in 2008 with their sales value.

  1. Create a new query to show the 2008 sales values of customers. The query is as follows:

    define measure 'Resellers'[Sales] = calculate('Reseller Sales'[USD Gross Sales], 'Dates'[Year]=2008)
    
    evaluate(
