SQL Server Analysis Services 2012 Cube Development Cookbook

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.

Managing cube-level security


You already learned how to define SSAS instance administrators and how to grant the necessary permission to cube developers. Now, it's time to secure the solution at the cube level so that each user is permitted to see only the data that they require to perform their job functions.

Each database could have multiple cubes. Cube-level data is also secured using roles, and (not surprisingly) cube-level security is defined on the Cubes tab.

How to do it...

Let's get started by performing the following steps:

  1. Open the role that you created in the previous recipe, navigate to the Cubes tab, and note the Access, Local Cube/Drillthrough Access and Process settings.

  2. Cube users could have three levels of access:

    • None: They cannot read any data from the cube

    • Read: They can read cube data

    • Read/Write: They can read cube data and write-back values only if write-back is enabled

  3. The DRILLTHROUGH permission allows role members to execute drillthrough actions and the DRILLTHROUGH MDX...
