Stardog really means it when they say you can act as if the walls of the silos are not there. Debuting in version 7 is what they call Virtual Transparency, which appropriately abstracts away from the user, whether that's an application developer, a business analyst, data scientist, or anyone else who needs data, the unnecessary details of where the data is or how it's stored. Data consumers simple write a logical query, i.e. "get all purchases made in the last 30 days in the mid-atlantic, within the Electronics department for more than $100" and Stardog's platform handles the details of accessing the data where it resides and returning a single, coherent, and most important, complete result.
