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 as text

Tabular modeling natively supports the import of files with extensions of text (.txt), comma separated values (.csv), and tab separated values (.tab). Once a file to import has been defined, the user can specify the delimiter (column separator), and the importing interface scans the file to estimate the underlying data types for each column. Finally, the interface finishes the import process by loading the data according to this specification.

Getting ready

A text file to simulate the output file for the sales record header has been created and is available from the online resources for this chapter. This file includes the sales_order_id, customer_id, employee_id, currency_id, customer_po_id, sales_territory_id, order_dt (order date), due_dt (due date), ship_dt (ship date), and sales_amount fields.

The file will be imported as a table into PowerPivot (and the tabular model). A screenshot of the file is shown as follows:
