در ادامه درباره نویسنده ایبوک الگوی DAX توضیحاتی آورده شده است.

Marco Russo and Alberto Ferrari are the two founders of SQLBI (http: //www.sqlbi.com), where they regularly publish articles about Microsoft Power Pivot, DAX, and SQL Server Analysis Services Tabular. They both provide consultancy and mentoring on business intelligence (BI), with a particular specialization in the Microsoft technologies related to BI. They have written several books and papers about these topics, with a particular mention of “SQLBI methodology” (http: //sql.bi/methodology), which is a complete methodology for designing and implementing the back end of a BI solution; and “The Many-to-Many Revolution” (http: //sql.bi/m2m), which is a paper dedicated to modeling patterns using many-to-many dimension relationships in SQL Server Analysis Services and Power Pivot. Marco and Alberto are also regular speakers at major international conferences, such as TechEd, PASS Summit, SQLRally, and SQLBits

What is a pattern?

A pattern is a general reusable solution to a commonly occurring problem.
In Microsoft Excel, you use patterns every day to build tables, charts, reports, dashboards, and more.

DAX Patterns is a collection of ready-to-use data models and formulas in DAX, which is the programming language of Power Pivot. Create your Excel data model faster by using a DAX pattern!

For courses in Probability and Random Processes.

Probability, Statistics, and Random Processes for Engineers, 4e is a useful text for electrical and computer engineers. This book is a comprehensive treatment of probability and random processes that, more than any other available source, combines rigor with accessibility. Beginning with the fundamentals of probability theory and requiring only college-level calculus, the book develops all the tools needed to understand more advanced topics such as random sequences, continuous-time random processes, and statistical signal processing.

The book progresses at a leisurely pace, never assuming more knowledge than contained in the material already covered. Rigor is established by developing all results from the basic axioms and carefully defining and discussing such advanced notions as stochastic convergence, stochastic integrals and resolution of stochastic processes.
