MDX and DAX-compare and contrast

MDX and DAX are both promoted as analytical languages.  Despite the initial confusion when DAX was announced, Microsoft sees both as a part of its BI strategy (at least, that’s what it told us last time we asked…).  So far, so good.  You want to keep up with the Microsoft approach to the BI world, so the obvious answer is to learn both.  And, let’s face it; they can’t be too dissimilar can they?  They are, after all, both analytical languages. 

Well it turns out they are very different.  Indeed, it would be difficult to imagine two languages, both designed to analyse data, that were more unalike.  This begs a number of questions.

“Why are they so different?”

“What fundamental features make them so different?”

“Who are they aimed at?”

“Given my interests and current skill set, which one should I learn first?”

“How can a single company come up with two such different languages?”

 “Who is to blame?”

Who can I sue about this?”

“Was it anything to do with the phone hacking scandal?”

This talk will answer all but the last three questions.  It is not designed to turn you into an expert in either language but it should give you a clear idea about the fundamental design principles behind both, what each was designed to do, how well it does it and if either or both are worth learning.

    Mark Whitehorn specialises in the areas of data science and BI.

     

    Mark works with national and international companies, designing BI systems and Data Science solutions.  In addition to his consultancy practice he has also acted as an expert witness in cases of patent infringement and for the police in cases of computer fraud.

     

    He is a well-recognised commentator on the computer world.  He is a regular contributor to The Register, has written numerous white papers and also eleven books on database and BI technology. The first one, Inside Relational Databases has been selling well since it was published in 1997 and is now in its third edition. It has also been translated into three languages. Another of his books FastTrack to MDX was co-written with the inventor of the language, Mosha Pasumansky. 

     

    Mark is also an associate with QA Ltd.  He has developed several of the company's courses (data science and big data course, database analysis and design, MDX, Dimensional modelling) and teaches them all.

    On the academic side, Mark is the emeritus Professor of Analytics at the University of Dundee where he designed and runs a Masters course in Data Science.  There he also works with the prestigious Lamond labs. applying BI and Data Science to proteomics

    For relaxation he collects, restores and races historic cars which keeps him out of too much trouble. He only wears a tie under duress, doesn't possess a suit that fits and unashamedly belongs to the beard-and-sandals school of computing.
