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.

Creating perspectives

In the prior recipes, we have restricted what the user sees by hiding tables and columns from client tools. This can remove clutter from the model and hide information that the user never needs to see (for example, the SecurityProfile table). However, in situations where the model contains distinctive subject areas, there may be a desire to expose only tables in those subject areas as particular views. This is achieved through perspectives.

A perspective allows a virtual model to be created over the existing model, so that the user has a choice of views for the model. As a view, the perspective inherits all security from the underlying model. Only the tables and columns that are shown in the view can be controlled. Further, data security cannot be applied directly against a perspective and visibility of the perspective cannot be defined by role. That is, the perspective cannot implement its own data security profile.
