Getting Started with SQL Server 2012 Cube Development

Overview of this book

Analysis Services have been the number one OLAP engine for years. With the increased focus on business intelligence solutions, there is a shortage of professionals in this area. Start your journey into becoming a BI developer using the popular tools included in every SQL Server installation. Getting Started with SQL Server 2012 Cube Development teaches you through clear step-by-step exercises to create business intelligence solutions using Analysis Services. The knowledge gained through these practical examples can immediately be applied to your real-world problems. Getting Started with SQL Server 2012 Cube Development begins with an introduction to business intelligence and Analysis Services, the world's most-used cube engine. Guiding you through easy-to-understand examples to become a cube developer. Learn how to create a cube including all the advanced features such as KPIs, calculated measures, and time intelligence. Security and performance tuning will also be explored. You will learn how to perform and automate core tasks like deployment and processing. The main focus is on multidimensional cubes, but the creation of in-memory models will also be covered. You will learn everything you need to get started with cube development using SQL Server 2012.

Configuring storage modes in Analysis Services

As explained in the introduction to Processing objects section in this chapter, processing reads data from the relational sources and stores it in Analysis Services. What gets stored is defined through storage modes. There are three main storage modes in Analysis Services and these are Multidimensional OLAP (MOLAP), Relational OLAP (ROLAP), and Hybrid OLAP (HOLAP).

MOLAP

In MOLAP, everything is stored in Analysis Services, both the detail data as well as all the aggregations. The data that you will see will be from the time of the latest processing, this means that you need to schedule a refresh from time to time through processing of the cube or database.

ROLAP

In ROLAP, nothing is stored in Analysis Services. Whenever you query the cube, a query will be sent down to the relational source. This means that you will always get the latest data and no processing needs to be done to fetch data from the source, as this is done at query time. As no data...
