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.

445 dates and irregularities

Manufacturing and retail companies often use a special type of calendar, which ensures that all months have an equal number of days. This is commonly called a 445 calendar, which indicates that a month is made of 4 weeks, with the next month comprising 4 weeks, and the final month (in the quarter) comprising of 5 weeks. The next quarter follows the same pattern of 2 x 4 weeks and then a 5-week month.

Month names in the 445 calendar do not always equate to the calendar month. The 445 calendar month of January may run into February, and December may run into January (in fact this is frequently the case). Further, the week can start on any day of the calendar week, and a 445 calendar's month never end on the same calendar day of a month.

Although there are variations of this pattern (454 and 544), the concepts and implications of the calendar are the same. It poses a challenge in the model because a year does not start or end on the same date, and the months do not...
