I read an interview question:
"In which format SSAS stores data?"
Well, I remeber having read, that ROLAP stores and operates their data and metadata in relational format (OLTP relational database) that permits to use SQL, above of only MDX for SSAS storage.
What are exactly relational and multi-dimensional (SSAS) formats?
What are details of their storage, resp., and what are the differences?
