      Based on the requirements above and the problems of the traditional solutions we have created a concept called the Data Lake to describe an optimal solution. If you think of a datamart as a store of bottled water – cleansed and packaged and structured for easy consumption – the data lake is a large body of water in a more natural state. The contents of the data lake stream in from a source to fill the lake, and various users of the lake can come to examine, dive in, or take samples.

      The difference between a data lake and a data warehouse is that in a data warehouse, the data is pre-categorized at the point of entry, which can dictate how it’s going to be analyzed.

      The data lake, in turn, supports a two-step process to analyze the data.
