"A massive, easily accessible data repository built on (relatively) inexpensive computer hardware for storing "big data". Unlike data marts, which are optimized for data analysis by storing only some attributes and dropping data below the level aggregation, a data lake is designed to retain all attributes, especially so when you do not yet know what the scope of data or its use will be."

- rjbwork 11y agoThe intended use is to be able to use things like Hadoop or other tabular text processing systems to glean information from enormous amounts of data, then once valuable insights are found, use the Data Lake source to process it into a form suitable for a data mart, or preferably, a data warehouse.
