If you have managed SQL Server or other relational database systems, you should be familiar with the unambiguous KILL
command that disconnects the offending session and terminates the query executed on that session. Analysis Services has a similar statement, though it uses a somewhat milder term, CANCEL
, perhaps more appropriate for the type of operation it performs. After all, the impact of terminating the session isn't always immediate, even in relational systems. If a user is running a large transaction affecting thousands or millions of records, it could take a long time to roll such transactions back. The CANCEL
command is also different from KILL
in a sense that it doesn't immediately terminate the session or query. Rather it tags the session to be terminated. SSAS periodically checks sessions and takes action on those sessions that have been tagged.

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.
