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.

Defining many-to-many relationships


Many-to-many relationships appear in a number of modeling situations. Perhaps, the most common scenario and explanation is that of a bank account and their owners. In this situation, a bank account can have many owners who are equally responsible for the balance. However, the owners can have different accounts. The challenge faced in tabular modeling is that the relationship includes a direction that does not actively filter the fact data. The use of the bridge table breaks the standard downstream filtering that is usually applied in a star schema.

This recipe demonstrates how to create the many-to-many relationship by extending the previous recipe to include store ownership. In this example, a reseller can be owned by one or more owners. Furthermore, each owner has an ownership interest (as a percentage interest in a reseller).

The following are the standard types of questions that the model is expected to answer:

  • How many stores does an owner have?

  • What...
