Best practice design tool for MDX queries is now available in MDX Studio.
One last thing to mention: Best practices are exactly what they are – best practices. It means, that most of the time using them you will be better off. However, they are absolute rules to be followed always. Sometimes there are exceptions from the rules. AS is a complex, feature-rich product, and MDX engine is probably the most sophisticated piece in it. Sometimes features interact in such a way, that some best practices might result in worse results. For example, one of the advices that MDX Studio will give is when it sees Filter(CrossJoin(…)), it will recommend using CrossJoin(Filter(…)) instead. It is common sense to reduce the size of the set before crossjoin’ing. But not only this is not always possible, but also there are rare cases where it would result in worse performance. So while you are encouraged to follow the best practices, always use them as a guide, and measure before and after applying the rules to make sure things do improve.
