Scenario: Your manager has asked you to provide statistics on database performance for the last quarter. You decide to query the Spotlight Statistics Repository to return file I/O statistics for the databases your manager is interested in.
To retrieve this data, you first browse the dimension tables to become familiar with the data in the Spotlight Statistics Repository. Once familiar, you write queries using the Spotlight stored procedures to get data from the fact table. You then refine the queries using custom T-SQL to retrieve more specific data from the Spotlight Statistics Repository.
