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.

Importing data from databases

Although tabular models support the import of data from a variety of sources, a relational database is still considered to be one of the primary methods of obtaining data. Unlike other sources (such as text files), where the structure may change from time to time, the data from a database is preferred because it conforms to a schema which is expected to remain constant. Furthermore, most operational systems store their data in a relational database format, and therefore, the database becomes a suitable source of data.

Tabular models may extract relational data through a generic connection on the machine, for example, Open DataBase Connectivity (ODBC), which is a standard method of data access, or by a connection based on a native driver (specific driver) stored in the model.


An ODBC connection also stores a connection within the model. However, the actual connection to the database is managed by the ODBC connection on the machine (rather than the tabular model...
