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.

Adding a calculated column

Calculated columns serve many purposes but are usually used to combine values from multiple columns or derive a new value from another column. We don't normally aggregate values or perform complex business logic in the same way that we would in a measure. The key concept is that calculated column logic is applied to each row in a table. Keep in mind that this can also add storage and memory overhead.

Getting ready

If you're working through the instructions in this chapter from start to finish, you should be in the right place to continue with the next step. Get in the habit of saving your work often. If you have the project open and you're looking at the model designer, just click on the Save All icon on the toolbar that looks like a stack of floppy disks. (I haven't saved anything to a floppy disk for a while, but somehow this remains the universal icon to save your work.)

Getting ready

If your project isn't already open, then open the project in SSDT...
