A precise definition of the term “data lake” is yet to be established, but it is clear that it is a broad concept that is not confined to a single usage scenario. There is, however, a tendency to use the term to refer primarily to data preparation and storage, or to an explorative environment.

In Europe, however, a response of 78 percent clearly shows that the data lake concept is primarily used as memory for raw and detail data.
