Analysis Services ROLAP for SQL Server Data Warehouses

Summary: This technical case study describes how the SQL Server® Customer Advisory Team (SQLCAT), in collaboration with SQL Server developers, tested and optimized a large Online Analytical Processing (OLAP) solution based on SQL Server 2008 Analysis Services by using the Relational OLAP (ROLAP) storage mode. The study examines ROLAP system requirements and usage scenarios, highlights advantages and disadvantages of ROLAP in comparison with Multidimensional OLAP (MOLAP), and evaluates various ROLAP-related data warehouse (DW) optimization techniques regarding their effectiveness and limitations.

This case study is for data warehouse architects, database administrators, and storage engineers, and assumes the audience is already familiar with the concepts of large-scale data warehouse designs for servers, storage subsystems, and databases. A high-level understanding of Analysis Services optimization techniques for cube processing and query performance is also helpful.
