A method provides access to a data entity having a basis version and the creation of derived versions. The method includes a creating procedure for creating a derived version, by carrying out one or more operations on the basis version, storing them, and accepting them. The method further includes a providing procedure for providing access to the derived version through first addresses mapped to second addresses of the basis version and of the accepted one or more operations, by reconstructing the derived version based on the basis version and the accepted one or more operations.
