Big Data is high-volume, high-speed, and/or high-variant information assets that require cost-effective, innovative forms of information processing that enable improved insights, decision-making, and process automation.

The data lake stores a large number of data in their raw format, i.e. unprocessed, from different sources in order to make them usable for Big Data analyses. This data can be structured, semi-structured or unstructured. The information is stored there until it is needed for an analytical evaluation. Data Lake Definition
