SSAS OLAP Design - Best Practices

Introduction This paper outlines the recommended best practices for designing OLAP databases in Microsoft SQL Server 2005 Analysis Services to better meet the functional and performance needs of users. Designing a database for Online Analytical Processing (OLAP) databases is very different from designing a database for Online Transaction Processing (OLTP) and requires a different approach for achieving optimal results. The best practices recommendations are grouped into the following sections: Data Source Design Best Practices Dimension Design Best Practices Cube Design Best Practices Partition Design Best Practices Aggregation Design Best Practices Within each section, these best practices are ordered roughly by priority, where priority is a combination of how important the best practice is and how often you must worry about it. Major topics not covered include best practices for the design of calculations and for server management and operations.  These two topics are s...

Enable Usage-Based Optimization in SSAS

Usage-Based Optimization is a fantastic feature in SSAS to improve the most frequently used MDX queries of any cube database. This feature is used to design aggregations based on actual user queries using Business Intelligence Development Studio. But when ever you try to design  Usage-Based Optimization  you might have seen all the options  disabled.  This uses the technique of creating aggregations on FREQUENTLY USED queries in the given time interval.  We can enable the options in Usage-Based Optimization wizard. Connect to SSAS using SSMS (Sql Server Management Studio). Right click on the server and select properties as shown below. set CreateQueryLogTable to  true. Set the value of  QueryLogConnectionString  to any database where you wish to store your queries. Set the value of  QueryLogSampling  to the appropriate value for your environment (the default value of 10 means every 10th query will be logged). The lowe...
