What is a Data Lake? On the early days of modern computation, computers of the 1950s, 60s, and 70s would collect data from physical repositories (cards, keyboard input and tapes) and deal with it in memory, meaning a virtual environment.
In the late 1970s, computers started to cluster data for processing within worksheet alike structures, the grandfather of DataBases. DataBases were to follow and the logic behind it was for data to be input in a logical manner according to previous human classification, so although raw data (in the sense it hadn’t been previously treated) went into the Database tables, the decision of what would fit where and why was based on human criteria.
