What this book covers
Chapter 1, Introduction to Multidimensional Data Model Design, discusses the value of business intelligence as well as challenges faced when undertaking a business intelligence project and how to overcome them. You will learn high-level differences between Analysis Services tabular and multidimensional models and when each is appropriate. Finally, you will learn the differences between star and snowflake schemas for dimensional modeling.
Chapter 2, Defining Analysis Services Dimensions, starts off by explaining how to define data sources and data source views. You will learn how to extend data source views beyond the model available in the relational database. The chapter's main focus is on teaching you how to build and customize most commonly encountered dimensions within the Analysis Services multidimensional model.
Chapter 3, Creating Analysis Services Cubes, explains how to define measure groups and measures while setting appropriate properties. You will learn how to relate database dimensions to each measure group and implement basic as well as advanced measure aggregation functions, including distinct count and semi-additive measures. The chapter also discusses cube file structures and teaches the most effective strategies for measure group partitioning and building aggregations. Finally, you will learn various methods of deploying your multidimensional projects to your Analysis Services instances.
Chapter 4, Extending and Customizing Cubes, builds on the foundation of cube development laid in Chapter 3, Creating Analysis Services Cubes. You will learn how to make your solutions more useful to the business by adding calculated measures, named sets, actions, key performance indicators, perspectives, translations, and measure expressions to your cubes.
Chapter 5, Optimizing Dimension and Cube Processing, teaches basic and advanced options for processing multidimensional objects through XMLA, SQL Server client tools, as well as using SQL Server Integration Services (SSIS). This chapter also demonstrates how you should monitor and tune processing performance.
Chapter 6, MDX, explains how to write the most commonly encountered Multidimensional Expressions (MDX) queries and calculations. You will learn how to return data on query axes, limit and sort query output, define calculations and named sets, and navigate dimension hierarchies. The chapter also explains the basic functions used within MDX scripts and introduces the framework for monitoring and tuning MDX queries.
Chapter 7, Analysis Services Security, teaches how to manage multidimensional model security at the Analysis Services instance, database, cube, dimension, and cell levels. In addition to basic role-based security, the chapter also includes a recipe for implementing dynamic security.
Chapter 8, Administering and Monitoring Analysis Services, starts off by providing an overview of Analysis Services configuration options. Next, you learn how to create and drop databases, monitor and troubleshoot Analysis Services instances, and check the size of each object. Additionally, you will learn various methods for scaling out your multidimensional business intelligence solutions using backup and restore, synchronization, and the detach and attach options.
Chapter 9, Using Tabular Models, teaches you how to define data sources and models and load data into Tabular Models. You will learn how to define hierarchies, define calculated measures, and extend the Tabular model using key performance indicators. The chapter also explains recommended strategies for processing, partitioning, and securing Tabular Models.
Chapter 10, DAX Calculations and Queries, introduces the reader to Data Analysis Expressions (DAX) fundamentals as it applies to defining calculations within the Tabular Model and querying the model. You will learn how to write calculated columns and measures in the Tabular Model designer and DAX queries within SQL Server Management Studio.
Chapter 11, Performance Tuning and Troubleshooting Tabular Models, discusses the Analysis Services Tabular Model's usability limits. The reader will learn about diagnosing issues, optimizing performance, and memory use using various tools for troubleshooting suboptimal performance, which include Windows Resource Monitor and SQL Server Profiler.
Appendix, Miscellaneous Analysis Services Topics, discusses various Analysis Services topics that don't lend themselves to effective presentation in a recipe format. The chapter teaches you about various dimension properties, as well as outlining considerations for multidimensional design when developers are not permitted to create objects in the relational data sources.
