    <p>I currently analyze our customer data and trends by a number of SQL queries; and the testing of a hypothesis can be time-expensive. </p> <p>For instance, we have a table of our customer info and a table of our customer service calls, indexed by customer. I'd like to find out if a particular cohort of customers had more CS issues than another; and if there is any correlation between customer service calls and increased cancel rates. </p> <p>I was looking into MS's BI studio, as we're running MSSQL 2008 already; but most of what I've read focuses on carefully constructed MDX cubes that aggregate numerical data; so in the above model, I'd have to build a cube of facts (number of CS calls and types) and then use the customer data as dimensions. Fair enough, but in the time it'd take me to do that, I could just write the query manually in TSQL.</p> <p>My DB is small enough that the speed gains from a separate datamart aren't necessary -- what I'm looking for is a flexible way of looking at my data, by creating a Customer 'Object' and tying all sorts of data, actions and numerical values to them. And I'd rather have the data extracted from my existing tables rather than having to ETL to a separate table. </p> <p>Ideally at some point, I'd be able to use Data Mining tools for predictive analysis, but right now I'm going after low hanging fruit -- do customers from this ad campaign cancel more than the other one; etc.</p> <p>Am I barking up the wrong tree with SQL Analysis Services/MDX cubes? Or does what I'm talking about not exist easily to begin with? Any advice, directions to products, or insight greatly appreciated.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
