There is a general misconception between Online Analytics and Processing - OLAP and Business Intelligence - BI systems. OLAP works more with operational data which is rarely clean and consistent. BI systems are learning systems and an attempt to design a BI as if it was OLAP is likely to botch. My understanding of Open Data is that it is a BI system which would not give a near real time data. However, users are able to query, report, analyse, mine, visualise and act. On the other hand, users in general would want to work with standard reports, therefore it is imperative for the technical team to create these data marts in advance. The general concern from the supply side should be how to make a BI more adaptive and not how to impose structure on it. With the current data sets users should be able to do much.

Typically open data has been processed prior to being 'opened' in order to clean it, anonymize it and make it useable outside of the platform that created it. I believe it is possible to provide data as open in a near real-time way when your infrastructure has been designed to do so. I would however hesitate to refer to open data as a system. It's a philosophy, a culture that is abstracted from whatever OLAP or BI infrastructure an organization uses. It's not technology, it's empowered by technology. “A piece of content or data is open if anyone is free to use, reuse, and
redistribute it — subject only, at most, to the requirement to attribute and/or share-alike.” opendefinition.org
