Each MDX query refers to one or more axes on which data should be returned. You can refer to an axis by its name (columns, rows, pages, and so on) or by its ordinal number, starting at zero. You cannot skip an axis, so each query must include columns (ordinal 0), but could also include rows (ordinal 1), pages (ordinal 2), and so on. The majority of frontend tools can only work with two axes, columns and rows, so don't let this scare you. The SELECT
clause of the query must include the definition of all the axes, and the FROM
clause defines a single cube (or perspective) from which you extract the data. The WHERE
clause contains a slicer limiting the data set specified in the query's SELECT
clause.

Overview of this book
Microsoft SQL Server is a relational database management system. As a database, it is a software product whose primary function is to store and retrieve data as requested by other software applications. SQL Server Analysis Services adds OLAP and data mining capabilities for SQL Server databases. OLAP (online analytical processing) is a technique for analyzing business data for effective business intelligence.
This practical guide teaches you how to build business intelligence solutions using Microsoft’s core product – SQL Server Analysis Services. The book covers the traditional multi-dimensional model which has been around for over a decade as well as the tabular model introduced with SQL Server 2012.
Starting with comparing MultiDimensional and tabular models – discussing the values and limitations of each, you will then cover the essential techniques for building dimensions and cubes. Following on from this, you will be introduced to more advanced topics, such as designing partitions and aggregations, implementing security, and synchronizing databases for solutions serving many users.
The book also covers administrative material, such as database backups, server configuration options, and monitoring and tuning performance. We also provide a primer on MultiDimensional eXpressions (MDX) as well as Data Analysis expressions (DAX) languages.
This book provides you with data cube development techniques, and also the ongoing monitoring and tuning for Analysis Services.
