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.

Managing connections and tables

The goal of the model designer should be to produce succinct models that are easily maintainable. This implies the re-use of objects (and structures) wherever possible. We have seen that it is relatively easy to import data into the model; however, the designer should also think about the maintenance of the model in the future. This recipe looks at how an existing model can be extended by adding additional data, and how a table can be altered once inside the model. This recipe is motivated by the maintenance of an existing table—that is, how do we change the import of a table which has already been specified? Additionally, as a point of practice, the modeler should re-use an existing connection that has been created, rather than create additional connections by continually importing tables using the same database settings.

Getting ready

This recipe uses the model that has been created in the prior recipe Importing data from databases.
