2. What is “Data Virtualization”?
"Data virtualization is the process of
offering data consumers a data access
interface that hides the technical
aspects of stored data, such as
location, storage structure, API, access
language, and storage technology."
— "Clearly Defining Data Virtualization, Data Federation and Data Integration“
