Ive read some documentation and its not 100% clear on what this means. I think people use the terminology differently. I take it to mean that you can have one main warehouse environment where you have a repository of your data, then you can publish parts of that data warehouse to individual data marts which are simply subsets of the data warehouse.

Are data marts OLAPs? or is the terminology used with transaction processing as well?
