I like the way the presenter explains the difference between SQL and MDX.
Understanding these differences is crucial for any developer who is interested in learning how to query OLAP cubes with the MultiDimensional eXpressions (MDX) language.
I found these really useful links and videos to help us get started with the basics:
- The Logic/Flow of MDX (a.k.a. How to Think in MDX) – LearnItFirst previous video
- Comparison of SQL and MDX
- Project Botticelli: MDX Basic Concepts
